I used hotbit but fortunately for me, I don't leave my coins on exchanges so I had no coin deposited on this exchange during the attempted hack, every one have always been saying it, not your keys, not your crypto, keeping coins in exchanges is highly risky as no exchange is bulletproof to hack, and no one knows when it will happen, this is why I always withdraw my coins to my private wallet immediately after buying them, most times, I even prefer to use decentralized exchanges over centralized cus they are safer.
