Cryptopia is the digital exchange known after the hack and the exchange announced it was closed shortly thereafter.
The exchange was notorious for being a less popular listing of cryptocurrencies that most other exchanges did not list. The interface of this exchange is simple and it is only suitable for amateur traders who prefer to venture into low liquidity coins.
The exchange was established in NewZealand. Initially the service was a cryptocurrency mining group but they have evolved into an exchange of their own.
