DMS.Mining is already cheaper than this.
Currently 0,015-0,016 for 5 Mh/s.
Seems the new PMB has no market...I just try to convince people do not buying those PMBs, otherwise will quickly lose your BTC.
A lot of people don't touch DMS.Mining , because it has a very complicated contract involving DMS.Selling and DMS.Purchase.
But DMS-Mining is about equal to a 5Mh/s bond. All the other stuff is used to bet against PMBs.
(Note: At this point DMS.Selling is about 2.4 times more expensive than DMS.Mining, so it's difficult to say which one will give a profit in the end and which one will be at loss)
