You are not far from the truth dude, the government already has the plan to force every crypto users on providing adequate KYC in order to track all our transactions so we don't make anonymous transactions again. This is not going to be an easy adoption of cryptocurrency by the government and we need to be prepared for what is to come by the time our privacy is taken away from us.
Talking about banks adopting cryptocurrency and providing crypto services for custom, this is going to come and it's not going to take much time from now. Every processes is already in place to make us follow their regulations so we don't have the option to carry out anonymous transactions or to completely stay anonymous.
Well, Bitcoin transactions aren't anonymous. Instead, they are pseudonymous. It's possible to link addresses to your identity based on blockchain activity. All part of Bitcoin's transparent design. KYC will only make matters worse, as it will eliminate the little privacy Bitcoin has left. Governments will only succeed in their plan if they manage to hold or control most of the BTC in circulation. Spot ETFs, Strategic Crypto Reserves, and CEXs are all attempts to centralize and make Bitcoin fully KYC-compliant.
Banks are getting in the game, not only for profit, but to help the government keep a trail of who deposits/withdrawals Bitcoin. As long as most of the Bitcoin is held in self-custodial wallets, we should have nothing to worry about.
