No chance of me making a ROI with these guys as things stand unfortunately.
I took my 1 year contract out on the 10th of June for 0.433 Btc for 2 Mhz (approximately $277.12).
So far, earnings in just under 3 months have come to $66. The rate of earnings is decreasing steadily however, with approximately only $11 earnt over the past 27 days!
I think if BTC price gets back above $720 dollars this should make a ROI, but if the price continues to stay low there is zero chance of making a ROI.
If however you do feel like experimenting with the service then please click my affiliate link, as if your confident on an increase in Btc price this should make you some profit.
