How to solve it?

This does not seem like too big of a problem to solve. 1) Banks dont like crypto because they will eventually loose out on credit card payment fees - which nets them billions in profit every year. So of course they want to play hard ball as far as this goes. 2) As the crypto economy becomes bigger in the next 10 years - you will not need to move your money outr of crypto to use it on the high street 3) New banks will not give crypto the same problems as existing banks.
