I think banks will continue to become more and more desperate; it will get worse before it gets better. Eventually I hope it will turn into a "if you can't beat them, join them" situation where they find that it makes more financial sense for them to support customers who use crypto.
Similar thing with legality - I'd bet that more nation states clamp down on it before eventually conceding defeat. I wouldn't expect it to be explicitly legal in all countries for a long time, if ever.
