It's a whole new world isn't it. When I first started, also not too long ago, I attempted to create an account with Poloniex but had a lot of trouble with the confirmation process. After several attempts I gave up. Sounds like I didn't miss out on much. Now I do most of my trading through Bittrex without any issues and Yobit for my beloved (I know never fall in love with a coin/stock, but I have :-) )NLC2.
