Crypto Market Notes:
Diabolus/Crypto Market are two markets run by the same team, apparently on the same server. Crypto Market had an information leak where any attempt to log in as an existing user revealed the status bar of that Diabolus account, listing their current number of orders, number of PMs, and Bitcoin balance, hence giving access to ground-truth estimates of market turnover and revenue.
Diabolus, Crypto Market, SR 3.0, Lunacy and Andromeda are all affiliated. According to DNstats.net, Crypto Market was last observed up on 12 February 2017, but there are complaints in January 2017 on Reddit so no hard date for final closure. In any case, the escrow funds apparently were not returned.
