BTC itself is central bank, BTC is money!
Banks are naturally afraid of competition, which will bring new competition to financial markets and replace some of the Banks' businesses!
Less banking means less profit!
Right. Being in crypto, we are our own bank. So its obvious that banks doesn't like bitcoin because they are going to lose potential profits from it. Imagine people not going into the usual route when moving money around. That's billions of dollars getting out of their hands.
So to eliminate competition, they will attack it. They are waging wars against bitcoin now and I think it will be a continuing battle. But bitcoin will not eliminate banks, and it has no intention to do in the future.
I agree with you, and aside from the reason that they don't want competition and that they would lose a big portion of profit, that fact that they can't manipulate it is really a big deal for them.
