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. However, having looked at my accounts you can buy and sell crypto directly within the app, you can all send it from Revolut elsewhere but as far as I can tell you can’t send crypto
to your Revolut account.
To the OP:
I have read your other threads now and a couple of questions:
1. Do you now have full access to the exchange accounts holding the crypto?
2. Do you have your own account to setup on any exchanges?
