Banks will always used any opportunities they have to discourage people's from investing in cryptocurency because when people invest in cryptocurrency it takes money from their hands. People no longer trust banks because they're no longer leaving their money in banks.
People are now investing in cryptocurrency and the banks sees this as a threat to their business so they'll use every opportunity to attack those people doing this which is why they're closing their banks accounts. Both the banks and the government don't like cryptocurrency.
They'll protect their fellow banks when they have financial problem and look for ways to make people to keep trusting banks because it benefits their businesses but when it's cryptocurency they act like all cryptocurency are bad like the ones that collapse, it's just the nature.
If you understand what cryptocurrency is (in decentralised manner) then its very easy to understand why government and Banks are not in favour of this new financial system. There is not much resistance for centralised system since they can easily manipulated and controlled. The government opposition to cryptocurrency wont be reduced in near future rather it will be more intense in coming days. Move your crypto assets to wallet if you don't want any government censorship.
