It's a bad idea to store bitcoins on an exchange, that is like the most common advice given to newbs. Of course you have to use exchanges though if you want to "cash" out or actively trade. BTC-e was a bit shady though, just because no one knew who owned it. I used them a bit in 2014.
I have exactly 0 bitcoins on an exchange, and when I do cash any of them out, I send them, and do my business within minutes of the exchange receiving them. So, very little time my bitcoins rely on the exchange security or whatnot.
