"CM's failure is the result of an exponential increase in mining difficultly. The situation was further aggravated by the fact that the value of BTC has increased six-fold over the last year or so, and by HashFast LLC, a major supplier of hardware to CM, going out of business (please see http://docs.ciphermine.com/HashFast%20bankruptcy%20notice.pdf)."
All of this is not a reason.
The price of BTC  is lower than it in Dec.2013.
The Kate is a fraud 100%.
