Verifying source of funds- my funds come from selling bitcoin



I bought bitcoin a few years ago and have been selling into my bank account (not via revolut). I have been selling at the exchange Bittylicious. Would you accept screenshots of a) my bank account showing receipts of funds and b) list of my trades on bittylicious which will match the receipt into my bank account?

Also, what are the highest limits I can get? I intend to use revolut to help me arbitrage between bitcoin exchanges. So I will be ‘topping up’ far more than the funds I actually have as they will go round and round.

Thanks in advance
