I've opened an account at Cryptopia a few days ago. Because there was a coin I wanted to buy which isn't on Bittrex.

There is a lot less volume on Cryptopia as compared to the bigger exchanges. But it's indeed very handy for those wanting to trade lesser known coins. And it's also a good thing for us to have various avenues when it comes to cryptos. I'm also going to get verified at Cryptopia. That will provide even more options now and in the future.
