I am quite amazed to hear this question, as to why you think it is not worth it. I mean a lot of users almost every single member of this forum might be using CEXs even if they are saying they are not. I mean, people who prefer to use DEXs and somehow have to use CEXs. Might come up with an alternative solution like maybe preferring CEXs with no KYC or a lesser level of KYC solutions.

I get the idea that you are more concerned about the fee not about the privacy, I don't think fee are that high on these centralized exchanges. I still uses a lot of the CEXs and all of them have different withdrawals rates, speaking of BTC especially, I think OKX is much better.
