Loki's a legit project with a so far impressive team. It's available to buy or sell for BTC on TradeOgre, Cryptopia & Altex Exchange. TradeOgre is a relatively new exchange that started in January 2018, they list most of the good cn-heavy coins so great for GPU miners. I had an unique experience with TradeOgre that I wanted to share so I decided to write a review about them on my dapp.tech blog.
