Tried to find my previous comments on Revolut, can't, so a summary:
1. Was a loyal customer, for some time. Actually moved from TransferWise to Revolut. Never had issues with crypto-related payments, cards were very slow when delivered outside of UK, but fee-wise, when transferring bank to bank, extremely good and quite fast depending on bank.
2. Several months back, they started blocking accounts of friends, this mainly to do with nationality and secondary sanctioning, although Revolut themselves often denied these were the reasons. They would freeze accounts and funds and then became deliberately difficult about it. I personally never got in trouble but didn't want to take the chance anymore so have stopped using their card.
3. Still only use them for transfers to some countries, but never their cards. And never their crypto tracking (as pointed out, you're buying and selling a tracker, not actual Bitcoin).
There are better products now. I'd look out for Bitwala's rejuvenated offerings, but don't take my word for it. Check out this useful list for a starter's guide (more like a EU bank account but it's for facilitation of crypto):
