So if bank wires to and from exchanges are banned by all banks, how is people going to put FIAT into crypto to fuel the growth and how are we going to cash out if almost no shop accepts crypto yet?

Don't take me wrong, I'm quite invested in cryptos so I don't want to spread FUD, but if other banks follow it is a very difficult situation, at least until decentralized exchanges are working, which I don't think it will be any time soon... and I still don't know how we will put the FIAT we have in the bank into crypto.
