Wow, why is there such a large price difference between Bittrex and Poloniex?
I think it has to do with the fact that Poloniex has disabled deposits and withdrawals
Thanks, makes sense since my last deposit took more than a week to get credited. Do you know if SJCX deposits at Bittrex go faster?
Answering myself: about 30 minutes and it was in my account

Do you happen to know why its disabled on poloniex? I want to transfer my balance to Bittrex.
And SCJX -> BTC -> Polo -> Bittrex -> BTC -> SCJX doesn't sound like a good move :p
As far as I know it has to do with the large increase in trading volume over the past few weeks. The published a statement saying that they had difficulties keeping up with demand and are in the process of scaling up.
For now I'd just recommend using bittrex, I've never had problems with them.
I tend to agree, Polo is becoming more and more unreliable for sending/withdrawing certain coins, Bittrex is the way to go!
