I find Poloniex to be a very risky exchange to hold coins on, in light of their history. Bittrex is a terrific exchange with extremely fast deposit/withdrawal times and great customer service. ipoMiner is in the process of asking Bittrex to add CinniCoin, so hopefully we will see it added there today
Also, ipoMiner has added a direct port for mining CinniCoin -- come mine it with us, and enjoy mining all the hottest new coins in the future!
I had BTC on poloniex when it got hacked and I use this exchange regularly now. Busconi is paying me back weekly and has made huge improvements with security. The advantage of Poloniex is the Trollbox. Do not underestimate it in promoting a coin. Bittrex has next to no volume for many of its coins. Poloniex delists coins that don't trade. Every coin has some "action." Also, most of the coins being added to Mintpal are on Poloniex prior.
Poloniex also has 3 times the volume in BTC traded and this is with half the number of coins.
As of now today's volume Poloniex: 24-hour Volume: 605.289 BTC Bittrex: Daily Volume: 19800 trades valued at 178.15 BTC
You know the only way for us to increase in users and volume is to have market movers stay and trade with us. We've only been operating for 7 weeks now and have continued growth in our volume. I'd like to think we provide a superior platform, but I'll leave that to you to decide
OH btw, if you want a troll box, you should just come sit in #bittrex on freenode with us ... Not a big fan of trollboxes on sites where you should be focused on trading
Thanks,
Richie
