I think I lost the crypto I had in my stormgain exchange account (StormGain has migrated its operation to the platform powered by YouHodler)
From now on I think I will only use exchanges that are on the top 50 or 100 by volume... or if you have other suggestions/filters when choosing an exchange?
If am using an exchange, I will only consider the first top five, secondly, i will only use them for trading and and have my entire assets on a non custodial wallet, which I will device a means to secure my wallet keys.
I don't know your reason for using an exchange but I think if you don't have a strong purpose for using them, then it's better you hold on the recommendation am going to give you to consider under non custodial wallet in which centralized exchanges are not included.
