For example, I know from my own experience that Germany is friendlier than Britain. What do I mean by this? I mean it is just easier to transfer money from exchanges to banks and the other way around, the German tax people are generally "cool" with people owning Bitcoin, plus you do not pay capital gains tax on any crypto held longer than a year. Meanwhile, British banks are all angsty and I have heard of people getting their accounts shut down because they transfer fiat to/from an exchange.
Yes, there were some reports of some of the UK banks cancelling services to customers involved in crypto trading, but I don't think it was necessarily due to those banks hating on crypto, but more about the fact that such transactions would fall under "suspicious" in their systems. That could mean that such transactions triggered internal investigations, and since the cost of employees' time is not cheap, keeping those customers would mean making losses, so it was easier to just kick them out.
But still, most major banks would not cause you any problems for transferring to/from crypto exchanges. And I think, as crypto becomes more mainstream, "unfriendly" banks will be changing their stance as well, if they haven't already.
Anyhow, just because a few private businesses are not very keen on crypto that doesn't mean the whole country is as well.
