If you're in Europe, I can recommend N26. They have a bank card that functions as a "credit card". Only you need to have a balance on it or the transactions won't go through, because the account is charged instantly.
do not ever use N26 for anything else than a credit card though, don't have your main account with them, they lock accounts without giving a (concrete) reason and are then unreachable.
It’s not a credit card.
It’s just a debit or prepaid programme with Visa or MasterCard.
The real solution is never to have a substantial amount of money on any single bank account. Even traditional banks will shut you down without explaining why if they suspect you of working with cryptocurrencies.
