Banks are obliged to follow policies in the country they are based on. Those policies are always regulated by a government. Come on guys, this shouldn't be a question. Banks know where the sources of counterfeit money have been feeding scams like Tether and they didn't care. They are ok to hold Cartel's funds until there is no government that knock at their door.
Excellent example. (just not exactly the way you expect it) Blockbuster: banks Netflix: disruptive Bitcoin Apple+, Disney+, CBS/NBC/ABC+, whatever+: other cryptos and forks So when Netflix was alone and a king it ruled the streaming world. Then the other networks caught on, started to keep their own series and films while copied Netflix business model, not licensed them to Netflix anymore and suddenly there WAS COMPETITION in Streamland!!! What happened to Bitc... I mean NFLX's stock price? It meteorically raised to 700 bucks from 5 (or whatever), and crashed to 230 now, because you know competition and over saturation. Just like Bitcoin. The Super Bowl ads signaled the end and the over saturation. The ponzi is running out of true believers. Competition is good for the customer, not so much for the business.
If you really believe that the banking system is actually threatened by crypto, you need a reality check. The small fringe group that actually believes in the tech & its power to displace the banking system is irrelevant in the large scheme of things.
You refusing to understand the global financial system, and the crypto world is a recurring theme, that much is obvious.
