Banks spent years talking down on Bitcoin, and are now scared of some coin's yield because it beats a typical .4% interest on a savings account. They're afraid people will move away from traditional savings accounts and small investment vehicles, where banks make a lot of money on their customer's money, and move to crypto. Solana for example offers 5-8% yield. This will be extremely attractive to many bank customers who see this in their bank account as an option. I would get in Bitcoin before the banks start acting. 99% of people aren't paying attention but the banks will eventually buy up all the bitcoin. Their customers will need it.
