Cryptopia is a relatively small exchange out of New Zealand. What they lack in volume they more than make up for in volume, it more than makes up for in range of altcoin assets.

In fact, there are some coins that one can only get on this exchange. They seem to have grown recently as demand has outstripped supply. They even had to close the exchange recently to new users.

There are many complaints online though of rather poor customer service. Perhaps this was a result of the exchange buckling under user demand.

What are your views of the exchange? Security and reliability?
