Bitcoin MMT (Magic Monetary Theory)

What if Bitcoin is nature's way of preserving itself?
Considering everything the ecosystem is going through presently, it seems plausible that what may seem like merely a new computer technology is actually much more in a wider view.
Stepping back, one may notice that everything that is happening in this moment is on purpose. There is no such thing as coincidence. In the highly egocentric western world, many people see themselves as outside of nature instead of part of it. The reason for this is the abandonment of certain parts of ourselves and surroundings, more or less because of the cultural programming implemented in us from a young age.
Glance back to the first boom of usefulness for Bitcoin. It played a massive role in supporting black market activity, making it a valuable tool for transferring wealth and illegal goods in a nuanced and relatively safe manner.
Arguably, plant medicines that have been used by humankind for thousands of years to evolve consciousness now deemed illegal by mainstream culture are so rooted in the subconscious of our species that those very organisms used those willing to explore the forbidden mystery within them to eventually create Bitcoin and propagate for the benefit of all living systems.
When a psychedelic compound such a psilocybin present in magic mushrooms is comsumed, it's very apparent that it dissolves one’s sense of self in a way not fathomable in any other form that is legal besides maybe meditation with much practice. It breaks one down to one's most simple self, an observer of the universe unfolding, leaving one scraping away for any bit of sanity that culture has peddled if the ego fights the experience in any way, lost in a loop of hellish abyss.
Once the realization is had that all one can do is let the experience happen as there is no use fighting what the substance is trying to reveal is submitted to, it is as though a huge weight is lifted, catapulting consciousness into a wild, ego shattering understanding of unconditional love and interconnection. Having such an experience surely causes any “rational” being to question the nature of reality with a more scrupulous eye.
In an age where it is becoming more apparent by the day that the current power structure is not only not serving the majority of people, but ultimately destroying one’s physical/mental/emotional/spiritual health, it is a dire time that people need to come together, back to a sense of balance.
As many know, the disparity of wealth in the world is wider than ever before. This is not by accident. The parasites at the top thrive on fear and greed to cultivate and maintain their power over the masses. Many tactics, including banning psychedelic organisms to keep people disconnected and unhappy with whom they truly are so to disempower, continues the endless cycle of chasing false hopes in order to do their bidding.
Fractional reserve banking, responsible namely for the US dollar is arguably the sole reason all of this is possible, as every person on the planet must spend the majority of their life finding ways to collect pieces of paper in hopes of survival.
That does not mean there is anything inherently wrong with money. In fact, it is a rather useful invention. The problem is most people hardly understand anything about fiat currency, yet slave away for it every day for the majority of their healthy life.
This is why Bitcoin was birthed. Its purpose is to expose the rampant fraud we're all subject to. Debt based money solely derives its value on faith, where which that earned today is worth less tomorrow, selling future generations prosperity away now.
Many people don't yet view Bitcoin as a reliable store of value, but can one imagine where it would be today if regulators didn't have the authority to step in and put restrictions on its usage? Namely, KYC & AML laws that bar people from buying/selling without a bank license and require exchanges to demand the identity of every user with multiple forms of government identification. So too with capital gains tax. These regulations solely function to slow the inevitable growth of this unstoppable technology. At its grassroots, none of that ever being needed for Bitcoin to function is how it was brought into mainstream view following eventual restrictions.
Arguably, if those laws weren’t placed upon Bitcoin, there would already be an even more thriving new economy backed by it firmly in place. Instead, it's being stunted by the currently insolvent and collapsing system that is built on the premise of "too big to fail" corporations that pillage the world's labor and resources so a few can live absurdly lavish lives.
Fact is, it is one’s birthright to freely exchange ideas and goods with anyone else voluntarily. When denied of such interactions, our very nature to be liberated is denied,which creates inevitable resistance and strife.
Looking at what many see as the solution to this corruption that causes such wealth disparity – the undeniable craving for unity and respect for the planet seen widely in the democratic-socialist movement in America calling for redistribution of wealth and addressing rampant pollution of the earth is partially misled in the sense it calls for more government intervention that relies on stealing from people. That is what allowed this mess to happen to begin with. America is already socialist for the “too big to fail” class in the form of endless money printing, claiming it is a capitalist nation where the rest of the people are deemed too small to survive, scrambling for the scraps that are supposed to trickle down though a rigged economy. What society actually needs is to go back basics with fulfilling simple living backed by sound money that can’t be manipulated by an either ignorant or conspiring ruling class.
As the Bitcoin motto goes, "don't trust, verify". As long as the system is propped up by infinitely printable money, it can be used to corrupt those put in power, continuing a war on the people around the world.
Everything that is going on right now is supposed to happen. For the exact same reason Bitcoin is trustworthy because it is mathematical, so too is the universe. Nature constantly breaks down to build itself back up, over and over again. In this time of uncertainty, on the cusp of watching society as we know it crumble, a new paradigm is unfolding.
It is no coincidence this is all happening as Bitcoin has more people interested in it than ever before. This is the beginning of a potentially very prosperous age, unfathomable to most in the current moment.
People are not meant to be domesticated, controlled by others granted higher status. We are all the same at the end of the day. Psychedelic experiences can reveal this truth of oneness; a push against mindlessly obeying authority that further attempts to rob critical thinking to create better life for all.
Just as mushroom mycelium works as a network to break down old organic material to feed the forest and all who inhabit it, the internet and Bitcoin network work to break down centralized control of information and money that no longer serve the ecosystem.
All in all, Bitcoin is a peaceful protest against the current system that is much needed. So too are consciousness shifting psychoactive plants that originally propagated the technology, as though to say to those that unjustly assert authority, “you fucked with the wrong organism. May the love be spread all around”!
Thanks for reading! One love.

Well I purchased btc from CoinGate/Simplex using a credit card and I am starting to regret. I thought it would be the "easiest way to buy btc with credit card" according to their website... So here's the process, they ask for your wallet address, then, all you credit card info, then a selfie of you holding the credit card, then they withdraw funds, and ask for more info like upload of image of you DL, as I was doing this the site crashed, but they withdrew the $$ from my bank account. I got one email from simplex stating--- basically they take your money without verifying!!! Like if you can't handle amount if transactions, DO NOT take peoples money. NOT COOL!!!
"Thank you for submitting your payment. It is currently being verified. Simplex payment ID: XXXX XXX XX X XXXX Please note the this verification process may take some time. We appreciate your patience, as we are fully committed to ensure you receive a quick response. So, what’s going on with your money now? Simplex is currently verifying your transaction. It is possible that you will notice a charge in your credit card account. This is only an authorization check, automatically made in order to reserve the amount in case the payment is approved. If the payment doesn't go through (cancelled, expired or failed), this authorization check will be voided in no more than 48 hours, and you will not see the charge in your account.

I saw this post as soon as I made €200 payment via Changelly and I was scared to death that I've lost money again. However, while I was here worrying and going through the post, little didi I know that an email had been sent to me that the verification was successful and that my BTC would be deposited into my wallet soon and voila, I checked my wallet and I found the BTC there. I'm talking about less than 20 minutes here guys, so you can't imagine my joy, it was as if somebody gave me money.
My take: Those that encountered problem could be due to the fact that they are mostly Non-European holders and that Simplex has problem linking well with USD cards, I live in Europe and they are European based company, so they might find it easier to integrate well with European SEPA cards (in my own case). It could also be that they had major transaction problems before which has now been resolved. All these are just my assumptions, so disregard anything that sounds like jargons t you.
Cheers.

Credit card charged after payment request cancellation from Changelly
I wanted to exchange money from Changelly using my credit card, so I went through the process. I was taken to SIMPLEX API and entered my details; however I did not get to upload my picture holding the card for verification and decided to CANCEL the payment.
To my surprise, my money was WITHDRAWN from my account regardless. I've checked with my bank and they have confirmed this.
I emailed support 12 hours ago and still waiting for someone to have the kindness to reply.
I received a follow up URL when I emailed support, however it does not go anywhere. I am also not allowed to login or register using my Changelly email address AND on top of that social media login does not work either.
I am getting very anxious due to the large number of complaints, so I am wondering how long to wait for a payment reversal transaction before initiating a dispute through my bank; I did not buy any coins and ended up with a charge of $2,072.69 NZD on my credit card.
Payment cancellation email I received was as follows:
Dear xxxx, Your payment request from Changelly has been cancelled. You chose to cancel the payment. Simplex payment ID: aa16338a-a0e9-448d-b6f4-7e85bbfe0279 For more information, contact us at... or visit our FAQ section at simplex.com/ faq. Please do not try to reach Simplex's support using any other method (such as social media), as you might be mislead by imposters ...
Should I hear from Simplex I'll let you all know by posting here and I am more than happy to amend my rating; at this stage this is purely based on the support I've received from them, and of course the unhappiness of my credit card being charged without having purchased anything
I'll appreciate any feedback from guys. Cheers, Jose.

I've been going through this same scenario as everyone else here. Went through Mycelium to by bitcoin on the 10th of this month. Was sent to simplex for verification. Stayed in touch with their customer service and was told it could take 2 to 3 days. Had to send photo of license and everything else. Was planning on contacting them again tomorrow and then having cc charge back if nothing happened.
Well I just received an email that my payment was cancelled due to changes in BTC rate. I'm happy to report that my money has been returned to my card (i use a secured cc cause I was a fool in my younger days, not that much has changed). I just wanted to report this to give some of you hope. The last 2 days I've been stressful as hell. It was less then $100 but for me that's a lot of money to lose. Good luck to you all.

A more appropriate description for simplex would be money launderers. I have made over 10 debit card transactions with Simplex - the charges are authorized by my bank and then Simplex, for some inexplicable reason, will credit back my account for that exact amount with no explanation given. I have completed all the required verifications so simplex knows that the charge is being made from my debit card. basically money goes from my bank to simplex and simplex returns that exact amount to my bank.
Give AwardShareReportSavelevel 1[deleted]1 point· 1 year ago
Was going to make a small purchase earlier (~$100) but I wasn't aware they would require a photo of my ID. This isn't happening, no chance in hell. The "live chat" available on their site is fully automated, makes no difference what your question is you'll get standard pre determined responses. I've received an e-mail stating my transaction has been cancelled due to my not providing the proper ID - in the same e-mail it says my card should not have been changed yet, even though it already has. Be careful with this one, SCAM.

I sent in almost 100 dollars. They of course wanted photos of my ID so of course I sent them. They immediately sent an email saying that they were not good enough quality try again. So I took pics of it again. Then 6 hours later then declined my payment and accused me of fraud, "called me a fraudster", but still charged my card.
Your payment request has been declined.
Please note that we do not disclose the reason for declined payments. This is because unfortunately we have seen these reasons being used by fraudsters to create fraudulent transactions.

Please note that your credit card has NOT been charged. The funds have been placed on authorization hold in order to reserve the amount in case the payment was approved. Since your transaction has been declined, this authorization check will be voided. This typically takes the bank 48-72 business hours (not including Saturday or Sunday). Please let us know if you do not see the funds released after that time.

What is the best way to organize all your addresses away from your device?

I want to be able to accept payments to my crypto wallets on a Ledger I'm going to set up, but am wondering the best way to store and organize my addresses away from my PC. I do a lot of sales away from my main PC, and if I can reliably provide my addresses I would essentially take any of the cryptos that can be hosted on my ledger. Anybody have a good idea of the best way to go about this??

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer.

Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins
Gemini Bitstamp LibertyX
GDAX Bitit Mycelium LocalTrader
Bitstamp Cex.io BitQuick
Kraken CoinMama WallofCoins
Xapo BitcoinOTC
Cex.io

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.

Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Mycelium Bitcoin Wallet 2.0 (HD) is out!!!

Mycelium 2.0 HD - Welcome to the future
Address reuse is not for me So I am waiting for HD For even greater satisfaction I want to label my transaction And then there is a third temptation Cold spend with zero confirmation That's why I beg you, please: Release! -- Jan Dreske (Mycelium Developer anxious to get this thing out to the public, who's birthday is today) 
Over the summer the Mycelium dev team has been working hard to make Mycelium 2.0 a reality. Our 200+ beta testers have given us great feedback and today, our biggest and most significant wallet update has finally been released for everyone.
Direct download: https://mycelium.com/bitcoinwallet On Google Play we use staged rollout, where it is released gradually over the next few days: https://play.google.com/store/apps/details?id=com.mycelium.wallet
New Features:
What does HD mean?
HD is short for Hierarchical Deterministic. Typically, bitcoin wallets generate each new bitcoin address from a unique random number, requiring a separate backup of each new address. To avoid losses from lack of backups, such wallets use a single bitcoin address for all your transactions. HD wallets instead use a “master seed” (a single large random number), to derive all future bitcoin addresses sequentially from that single seed. This means that you only need to make a backup once, and all the keys generated by an HD wallet can be restored at any time in the future just from that single master seed. HD wallets greatly improve your privacy by being able to keep generating new addresses. If you use the same address continuously all your transactions will be associated with a single address, and because all bitcoin transactions are public anyone can see what addresses you are sending funds to, and calculate your total balance. With an HD account new addresses are created whenever you send and receive funds, making your transaction activity and total balance very hard to track.
But I liked it the way it was! Will I have to change the way I use it?
All your keys, addresses and address book entries will be retained when you upgrade your app. The tab previously named “Keys” has been renamed to “Accounts.” Your old bitcoin addresses will become single address accounts, and you can continue to use them as before. We do advise that you switch to new HD accounts, though. You will also see your first empty HD account, which you can start using right away.
What about previous backups? Do my old ones still work?
Yes. You can still import keys and addresses you backed up with the previous version of Mycelium Wallet. However, we have removed the ability to create backups of single keys, or create new single addresses accounts. Instead, we advise you to backup your master seed and move your funds to the new HD wallet. As long as you keep your old backups, though, you will be able to recover your legacy accounts using Mycelium. To import a private key, switch to the “Accounts” tab, tap the icon with a key and plus symbol in the upper right corner, and select “Advanced”. Then scan your encrypted private key and enter the password.
Will I be able to continue to use my current Local Trader identity?
Yes. Your Local Trader identity will get carried over to the new version when upgrading along with your private keys.
How do I make a backup?
To create a backup, either tap the “Secure My Funds” button on the main page, or choose “backup” from the menu. You will be shown a list of words, one after the other. Write those words down with pen & paper. You then have to type in the words again, to make sure you got everything right. Store this word list in a safe place! Anybody who obtains this list can access current and future funds in your wallet! Note: The backup procedure only backs up your HD accounts. Your classic single address accounts are not part of this backup procedure.
How do I restore a backup?
If your phone is lost or damaged you can make a fresh install of the mycelium wallet on a different device. Upon startup, choose “Restore Backup”. Choose 12 as the length of your word list, and let the “password” checkbox unchecked, and proceed to enter your word list. This recreates your master seed and automatically creates and synchronizes your first HD account. It might take some time until your first account is synchronized and the balance updates. If you had more than one account, navigate to the “Accounts” tab, tap the button with a key icon and plus on the upper right corner, and choose “Add HD Account” to re-create your second account, etc. Note: This procedure only restores your HD accounts. To restore your classic accounts you have to manually import each key/address by going to the Accounts tab, click the + button, select Advanced, and then Import. If your previous Mycelium installation had a Local Trader account you can recreate your trader account and data by clicking “Buy/Sell Bitcoins”, select the “My Info” tab, click “Create” and select the account that your local trader identity was associated with.
Can I restore a BIP44 wallet created with other software?
Yes. When you start a fresh install of the app you get the option to restore a backup. You can choose between word lists lengths of 12, 18, or 24 words, and also supply an optional password in accordance with BIP39. This way you can restore all HD accounts generated by other wallets compatible with BIP44 and BIP39. For instance, this allows you to import your TREZOR word list in case your device was lost or damaged so you can quickly move your funds to safety.

Mycelium 2.0 Alpha with full HD support launched for testnet

Over the summer we have been working hard to get Mycelium 2.0 with HD support ready. The Alpha version has been submitted for testnet and is available on Google Play now: https://play.google.com/store/apps/details?id=com.mycelium.testnetwallet
The same signed APK can be downloaded here: http://mycelium.com/assets/btcwallet/mbw-testnet-release-2.0.0-ALPHA3build20003.apk
What's different?
At a glance it looks like it used to except that the Keys tab is renamed to Accounts, and all your keys/addresses are called accounts. So all your private keys and read-only addresses are preserved fully backwards compatible.
Beneath the UI everything has changed.
What is new?
You can have as many accounts as you like (HD or not), but your wallet will be slower if you have many. Since HD accounts produce unlimited amounts of new addresses as you use them you will eventually feel the effect. To mitigate that you can archive accounts as they grow heavy. You can activate archived accounts as you wish.
TL;DR
Help us testing the testnet version of Mycelium 2.0 to get the production version out faster If you need testnet coins strike a deal with Virtual Trader by clicking "Buy / Sell Bitcoin"

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
Some great introductions for new users are My first bitcoin, Bitcoin explained and ELI5 Bitcoin. Also, the following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
Also have to give mention to Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series. Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute. Bitcoin statistics can be found here, here and here. Developer resources can be found here, here and here. Peer-reviewed research papers can be found here. Potential upcoming protocol improvements here. Scaling resources here. The number of times Bitcoin was declared dead by the media can be found here (LOL!), and of course Satoshi Nakamoto's whitepaper that started it all! :)

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Samouari BreadWallet Electrum
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

BCH sent to P2WPKH-P2SH Address, recovery shows mixed results...

I have a case here where a client of mine used a BitCoin ATM, and inadvertently used the 'BitCoin CASH' option instead of 'BitCoin', when he was using himself a Mycelium HD Wallet on a SegWit Address. Mistakes were made, but we have held onto the hope that at somepoint recovery would be possible.

With the May 15 Fork and the addition of SegWit recovery to the BitcoinABC codebase, recovery became possible, and the BCH chain survived an attempt at a double-spend attack by some thrifty miner(s) who realized that they could swoop in and take some of these trapped coins.

Since then, a couple guides have arisen that give an explanation of how to do a recovery, if those BCH sent to a 3xxxx Segwit address have the correct 'things', primarily a corresponding private key.

Here is my question/problem --- my BCH wallet is an HD Wallet created in Mycellium, and this was the 2nd 'account' in the wallet, and the 'second' key in that account. The BCH Derivation code is m/49'/0'/1'/0/1 . Problem is, I can only find a private key corresponding to the p2wskh-ps2h: key, and the p2sh: key in not importable in to Electron Cash wallet. How can I find a private key that corresponds to that wallet location in Electron Cash?

Here are some details:
3CSUDH5yW1KHJmMDHfCCWShWgJkbVnfvnJ
address the BCH was sent to... now, this address had BCH AND BTC sent to it at some point, and the BTC was spent, revealing the public key hash.
18dWL1ANKPwrhnbvNhrTDy8sxUzDGZ7YH2 is the 'legacy address' that Electron Cash spits out when I put the p2wskh-ps2h:"private key'

bitcoincash:pp67j94cfvnfg727etymlst9jts3uhfdkurqvtj2un is the public key address that Electron Cash shows the transaction occured on. If you put that key into the Electron Cash as a 'watch only' wallet, it still shows a 0.58 BCH Balance.

Problem is, I can't find out how to retrieve the private key for this address... the private key for 3CSUDH5yW1KHJmMDHfCCWShWgJkbVnfvnJ just gives the 18dWL1ANKPwrhnbvNhrTDy8sxUzDGZ7YH2 address in Electron Cash instead of bitcoincash:pp67j94cfvnfg727etymlst9jts3uhfdkurqvtj2un ....

Anyone think that have a hint where to check next? I have tried the BIP39 recovery site and can generate xprv/yprv keys, but none of these seem to be giving me the private key needed for the Derivation set of the HD wallet. Any help would be greatly appreciated!

Sweeping a Wallet

I have BTC in a Coinomi wallet, and was able to claim BCH, but also have a Mycelium wallet that held BTC before the fork. I found the procedure to sweep the Mycelium wallet to Coinomi to claim the BCH: https://coinomi.freshdesk.com/support/solutions/articles/29000013719-how-to-get-bitcoin-cash-from-many-wallet-software-services-with-coinomi
But I'm not really understanding the mechanics of what is going on if I do that, so I've been reluctant to try. Whenever I research sweeping wallets, it's usually discussed in terms of a paper wallet that shouldn't be used again after the sweep. So my question is, if I sweep the Mycelium wallet to get the BCH, can I not keep using that wallet since the private keys have somehow been compromised? (I thought I understood private keys, but I obviously don't since I can't wrap my mind around what's actually happening behind the scenes, so any explanations would be much appreciated!)

A little confused about my new Trezor

I'm completely new to the entire Bitcoin / Ethereum scene, but have recently been purchasing a little of both each week. I decided that a Trezor would be a good way to store them, as opposed to having them sitting with Coinbase. My problem is that I have a few basic questions that I can't seem to find the answer to anywhere.
The most basic is about how to transfer funds. If I'm understanding this right, I'll follow the instructions in the manual and create my wallet and set up the device. Then I just go to Coinbase and send the funds to the wallet address?
If that's the case, how do they actually get to the Trezor from the wallet? Do I have to send them from the Trezor website to the device, or is the website just a pass through? If it is just a pass through, that would mean that anytime I want to receive funds that the Trezor has to be plugged in and I have to be logged into my account?
What happens if someone sends me Bitcoin when I'm not logged in and have the device connected?
Is there a walk-through on how to transfer Ethereum to the device? The website says you can, but there isn't anything in the manual describing the process.
Is it advisable to send a very small amount of both to the Trezor until I figure out how it works? The last thing I need is to accidentally have them sent somewhere they shouldn't go and be lost forever.
Thanks for your patience, as this is all new to me.

Better way to send bitcoin to someone without a wallet?

So I'm at a wedding and I've been chatting up Bitcoin with my cousin, and now he wants to try it. So I'm ready to send him some coins, but this is not so simple. He has to: open the app store, find a bitcoin wallet that he likes, download that, open it, go through some setup process with warnings and such about backing up and losing his coins, create a passcode which he might forget, etc. Then after that I have to tell him to click on the "receive" button (or whatever that wallet has) and hold up his phone for me to scan the QR.
What I would like to do: Open a website on my phone that lets me enter his email address or phone number which then generates a receiving address for me to copy and paste into my wallet so that I can send the coins to that address. So the work is all on me.
After I send the coins he would get an email or SMS with a link which would let him, open a minimal "web enabled" wallet that does not require login (link would be all they need). Once they click the link it immediately shows them their balance. So they use tools they already know (email, sms, web).
Blockchain My Wallet has some features like this (send via email), but only if you have a My Wallet account already and then the setup process on the receiving side is still complex. Blockchain doesn't even let you send via email from their iOS app (AFAIK).
Of course there are issues, like would this service know the private key they generate for the recipient, and is there a way to avoid that? Email snooping, is also a security issue, etc. But the ease of sending anyone bitcoins, with no requirement for them to setup anything in advance and no requirement for me to use a particular wallet for sending might overcome some of these issues (if they can't be solved).
I'm curious to know of other solutions out there for this (is anyone "killing it"?) and if other bitcoiners would find this useful.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Been lurking for a few weeks. I finally took the plunge and I just installed Mycelium on my Android phone. Any advice? I'm in the EU.

Overwhelmed trying to choose a wallet

I want to start buying bitcoin, but I'm stuck trying to choose a wallet. I guess I'm worried about getting hacked and losing everything. Initially i just want to buy a small amount here and there and hold, but eventually I might want to actually spend some once I'm more comfortable with it. I'll probably be mostly buying on Android or from a Windows desktop
Also, It seems to me like most people have multiple wallets? I assume you can just send and receive them to different addresses? And could I have multiple wallets on the same app? Could someone enlighten a little to how this works

Mycelium Gear has a "donate to Naked Heart foundation" widget. I've sent funds. Do we have any evidence those Bitcoins have been sent to the foundation?

I'm honestly concerned. I've donated some bitcoins and I have reasons to suspect they were never transferred to the Naked Heart foundation. Can anyone from the Naked Heart foundation confirm they received the funds? I've actually contacted them, but never heard back. Is Mycelium scamming people who in good will donated to the foundation?

How is my offline private key private once I make a payment?

I'd like to buy bitcoins. I plan to generate my private key offline and print/save to USB sticks. Since it was never online, it can't be stolen. But if I want to buy something with my bitcoins, then I need to use my private key right? So won't it then be online and undo all the effort I did of keeping it offline?
