I think it is because of decentralization which banks cannot gain control as we all know that banks are centralized and are regulated which crypto doesn't not unless it is purchased in a SEC compliant exchanges that was regulated. Competetion would be another reason as well.
Well, banks don't see much of a threat on Bitcoin as they did back in the early days. The number of centralized exchanges dominating the market, and the recent spot ETFs approval are moving BTC away from its core principles. Banks should be more than happy now that "Wall Street" is in the game. The whole purpose was to eliminate the middleman, but it seems we're going one step backwards. Satoshi didn't want this.
Unfortunately, human greed has led us to a point where we are right now. The vast majority of people are into Bitcoin and other cryptocurrencies to make money. NOT because they believe in the tech. With CBDCs poised to rule the world, we can say bye-bye to the crypto revolution for good.
