I think the future is in UK after the Brexit. UK would love to make itself a centre of crypto to extend its already very strong finance section in its economy.
I think you are absolutely right. UK is very open minded when talking about money. They will do anything to invite more capital. And after Brexit they will be even more open minded.
I think it'll be a toss up between UK and Sweden in terms of who will adopt crypto first as an actual currency.
Though what's important is that other countries follow suit of course.
