Again we saw an exchange got hacked. There would be nothing to hack there if people didn't keep their coins on exchanges! For the love of Dog (lol), don't keep your coins on exchanges, start practicing safety, this is your investment we are talking about!
If you are heavily invested in crypto, its always better to invest in a hardware wallet and use it for storing your coins. I personally prefer Ledger, however, Trezor works great too. Choice is yours, invest wisely, keep your coins, private keys safe. Never trust an exchange just because its big. Hacks happen on big exchanges.
