As the old rule-of-thumb goes, NEVER keep your coins on an exchange. This also helps with much value
Also, I would like to add the information to keep your coins into a cold-wallet (desktop, trezor and so on)
This way helps me survive the fall of Cryptopia, Cryptsy, VirWoX and others
Craptsy was the first exchange that taught me to never keep non-trading funds on the exchange. Lost almost 22 LTC and 1 BTC and few other alt though it was not much money during those days but, it did hurt to see them gone lol.
