(Hackernoon, by Kirill Shilov)

"To sum everything up, the rapid development of the crypto market has generated a variety of business models.

"Unfortunately, Bitcoin went into a downward trend around January. This trend combined with the heavily rising difficulty around April and May reduced mining outputs even further. As a result, some user contracts are now mining less than the daily maintenance fee requires to be covered, and thus they entered the 60 days grace period, after which open-ended contracts will get terminated."
