Bittrex & Kraken, although I haven't used Kraken, I have an account there. Do not put all your eggs in one basket, exchange. You're only setting yourself up for problems. Bittrex has a lot of coins Polo doesn't have too, Waves, Music, XVG, etc.
Which coins were you moving? I've never had problems moving $BTC.
Best of luck.
This is good to know, I'm a newbie and was looking at exchanges myself!
Welcome to crypto!
There are several other exchanges out there beyond the big 3, I just haven't used them so I don't mention them yet.
Don't panic at these flash crashes. They've been happening across exchanges because of the exploding growth everyone is experiencing, Coinbase, Poloniex, Kraken. I don't think Bittrex has had a major crash yet, but it could happen any day as more and more people are looking for other exchanges.
Always have your wallets outside of the exchanges as well.
Good point!
33% exchange

Yeah, you should probably dodge that bullet.
I have Kraken for another currency. Seems to be working well. That's a good point :)
Works well for now, until they get busy days were they get super laggy or cannot even log in. Also, I really don't like how they increased the transfer fees for bitcoin lately. First multiply the bitcoin fee FIVE times, then after people complained, they dropped it to 2x. So now it's sitting at 0.001BTC, but who knows for how long...
