I have a bad experience with Kuchoin, I have an account from 2018 and then the end of 2018 never logged in until the end of 2021 or about 3 years, still leaving several altcoins such as Monaco Card, Eth, and several Altcoins, when I check it now around $ 550, But when I was going to log in at the end of 2021 they block and ask for KYC, I complete KYC after successful and I can login it turns out zero balance, no history of deposit and withdrawal and the deposit address changes and the balance in the old wallet is moved.
