Ugh, I wish there was a REALLY reliable exchange/wallet service with as many cryptos as Bittrex. I can't say I have much personal experience with services yet compared to a lot of users here, but it seems like none are perfect. However, the consensus seems to be that Bittrex is our best bet to use.
Just scary that a service that could have a large part of someone's "nest egg" seeming unreliable often :(/
