At first, thanks for telling us where you are based. It's nice to associate a living place to "avatars". For now, I am based in Northern Italy.
About customers, yes, it depends onto your customer base and how much "perceive innovation" can be brought to them. Currently I am close to some companies willing to use cryptos but they have specific purposes: some of them are B2B with international suppliers/customers others are in the tech field. So, there are some business areas that are readier for this innovation.
About the second point, I am currently working with a niche provider that supports Europe. I am getting info if they support UK as well.
