Exchanges now are not a safe place for storing crypto. If you have money you can buy Ledger(strongly recommend), or use MEW for ETH and ERC-20 tokens. Or use blockchain wallet of crypto which you have.
Cryptopia is perfect example for this case. After news about hacked exchanges i also withdrew coins to my ledger wallet. Even blockchain online wallet is not safe for storing crypto and there are bad rumors about their reliability. Cryptopia is perfect example for this case.
The big mistake people are doing in this situation is investing and get very quickly but it is not good for them also without getting huge profit how we can develop our monthly income so cold for at least some more extra time it will good for the development and very useful for stability of cryptocurrency especially Bitcoin so holding for long term investment will be the good idea now.
Some are storing their money on exchanges as it's easier to access and they can also trade easily.
Though there is a risk but they are willing to take that risk and therefore for whatever happen, in case exchange
will be hack, they should not blame anyone, it should be themselves.
It's alright to store in exchanges, make sure you don't only trust one for your assets, and for long term hold, better put it in a hard wallet for proper safekeeping.
