I spent what DOT I had on some votes earlier on when I seen it added to the voting list, Cryptopia is a great exchange and they also recently upgraded their layout to a much more faster and interactive one especially with market parings for coins being all in one section when you search the currency you wish to trade.
Yes it is. Been trading and mining there for a while now. Great bunch of people there too and very helpful. Glad that we could get Benji on there.
