Comments – PBMining has been offering a competitive price, which is why we decided to give them a try. So far, by week 4 of our purchase, our initial approx. 0.5 BTC investment for 100 GH/s (price for GH/s has been going down, and is currently at 0.0036 BTC/GHs as of June 29th, 2014) has returned 0.122BTC, or approx. 24% ROI.
So, far there has been no trouble at all, and weekly payouts have been coming in without delay.
However, we still find PBMining to be a 'high-risk investment' since there are no mentions of company address (they may not be a company!) nor payment options in USD (this is unusual even amongst cloud mining services), nor information on mining operations.
We believe that all these issues will improve as the cloud-mining industry matures, and companies with great pricing plus great transparency emerge over time.
