Just don't store it on an exchange.
Don't want to get goxxed now do you.
It depends.
If you use them as a store of value, you shouldn't keep them on an exchange.
On the other side, bitstamp customers were not really goxxed in the end, so the market is getting better.
If you want to use them for sporadic transactions or store of value blockchain.info is a pretty good choice since there are good security measures taken. (if we forget about
the breach a few weeks ago)
