Mate Just like you I'm also disappointed with these expensive fees, In both Bitcoin and Ethereum but we can't do anything about it. I think most of us the small-scale users and traders are the most affected by these expensive fees and Instead of leaving why just look for something that fits your needs temporarily, just return to Bitcoin and Ethereum if the transaction fees were normalized. I think it is a better solution than to leave because thats what I'm doing now in the meantime.
