There is no banks in this world accepts cryptocurrency as their deposit so obviously you have to sell it and I don't know what is wrong with selling and taking the cash from your bank account.
You can move the funds to any exchange and convert into fiat there or go to p2p exchanges where you can directly sell the funds to buyer and the funds will be coming to your bank account,once you confirm the payment received then you can release the escrow.
Actually Revolut (UK based FinTech) support both cash and crypto accounts all in their mobile app so it is
theoretically possible.
Its more like a wallet not the bank account because you can't receive funds from an external wallet, for example if I have a Revolut account I can't able to deposits bitcoins into my accounts from an electrum wallet, you can only receive from another revolut user of can buy from their platform using their exchange.
Can I receive cryptocurrencies sent to my Revolut account?
You can receive cryptocurrency sent by another Revolut user.
However, you will not be able to receive cryptocurrencies sent from outside the Revolut platform (i.e. from an external wallet).
