I dont get why this coin is still mined.
Exactly.

Also there is few fat buy orders on bittrex

Something is wrong behind this coin. Price should drop right now but someone or a group keep mining & also block the price with large buy orders. Where is Logic ? Something is behind the scene.
I guess it is mining pool not a group especially considering hashrate fluctuation. Also a few fat orders appeared on bittrex a long time ago. I guess someone put an buy order and forgot about it or plan to dump crypt again. In any case crypt anon solution if we get any should be much much better that others have since competition become a lot stronger. I truly hope crypt will not become a new scam coin (but considering my previous experience looks like crypt is a scam coin)
There is a Group called the Crypt Devs mining against small pools. 1GHash vs 20GHash+ using Coin Switching when the Diff Spikes. MindFox is no longer going to work on the Anon solution so it may not be any better than any other coin unless Crypt is just saying this now to Hoard the coin knowing they have a perfectly working solution already. They said their solution was brilliantly simple when they started the coin with nothing but a White Paper and a well known person called MindFox who was not being paid anything. Which we didn't know until after the Fraud at GitHub was perpetrated.
