Bitcoin privacy exists as long as you do not link your addresses to your identity and do not exchange Bitcoin for fiat money using a bank card. CoinJoin, like other mixers, already has some problems with regulators and exchanges, so it is better not to use these technologies if you do not want your funds to be marked as dirty and excluded from exchange. If you exclude cash from the financial system, you can remain anonymous only within the Bitcoin network. So if everything goes as you think, we are all in for a lot of inconvenience.
That’s right. If you wanna do it that way, go through P2P since there’s no KYC needed. It might not lead to real mass adoption, but if we’re talking about privacy, that’s the route to take. And even if Bitcoin fails as a legal tender, it doesn’t really matter, people don’t care about the title. What matters is it still works, and we can still use it to transact through its decentralized nature.
Yep.
Adoption comes a long way, and it never stops - it only can be halted for the time being, and eventually, it will reach its natural conclusion.
