I had $468 in usdc that disappeared as I was trying to convert to BTC. My transaction history says I sent it out.. But I didn't. Ive left two emails with support and Sunday morning they addressed the issue and refunded me in a few hours. The fee's ain't cheap but maybe you can bink a nice lick like me on the rain fall. Overall I feel they are legit. I got 468 for having a verified account. They got 5 stars in my opinion.
