I second about Bitmart, well not biased but based on my experience. I just recently got aware that one of my hold coins for years got listed on that exchange. Since the price was decent, high gas fees can be covered so I did try to sign up disregarding possible risk since I have no choice in the first place. If I can withdraw it then good and if not, it's fine. The whole process is smooth so I can say they are good.

But the only downside is, (not actually a downside but for those who don't want KYC), it needs KYC to verify. I comply on the Intermediate level and the process was fast.
