Btc in Revolut - can I somehow avoid fees

When it comes to the time when I want to side step out if btc, when it goes down, is there a way to avoid actually selling and losing so much to the fees and spread? How does swapping work? Are the same fees payable? My profit and amount of btc is getting battered by these losses. Thank you.

Also, any safe smaller cap shills that still haven’t pumped or could be a continuation after btc? :)
