Ouh, I keep noticing the same, if you do simple mistake in any of the exchanges, because of the huge demand, it's hard for them to reply and fix the issues. That's the growth challenge.

Thankfully yes, there are a lot of exchanges, keeping coins in cold storage or your own wallets always works. 

I guess just a reminder to be careful and really great @g-dubs, that you were smart enough to put most in cold storage.

Good reminder for everyone else (including me) to be careful and watch the coins like a hawk :D
