Oasis Market

• Not to be confused with MakerDAO's OasisDex
• From this article:

"One of the first darknet markets to experiment with Monero payments went by the name of Oasis. Past tense is more than warranted here, as the platform suddenly went dark in late 2016. It appears a lot of users were effectively scammed before the company disappeared, which resulted in at least 150 Bitcoin in losses. The amount of stolen XMR was never officially confirmed, but it is believed it was quite substantial.

Things had been looking quite positive for Oasis, as many people felt the platform was legitimate. Moreover, its user base continued to grow exponentially, and Oasis could have turned into one of the primary darknet marketplaces we know today. Unfortunately, the administrators took the easy way out and stole money in the process. It serves as a stark warning for anyone using darknet markets, that much is evident."
