I know Revolut added Cryptocurrencies to their service: https://blog.revolut.com/what-you-really-need-to-know-about-revolut-crypto-rates/

Unfortunately I think you can only buy/sell on their service, and not send/receive crypto yet (silly) - but that feature has to be around the corner. Might be worth getting an account setup for when they do add the feature.

I haven't used their Crypto feature, but I've used Revolut quite a bit when travelling because they exchange fiat at market rates at time of purchase.
