Spondoolies Tech seems to indicate that PBmining it's a ponzi:
This is not endorsement to buy CBCM, but I look at PBMINING cost. The electricity alone for 5 years cost a lot more than the contract cost per $/GHs
Either it is a pyramid or they expect to replace with new hardware at an unrealistic rate. Do the math.

i am also confused with their low rates.No one can provide this service on these rates.it looks like a ponzi or hyip
low rates?? its over 2.5usd per gh??? relative speaking low, but per gh with the eficiency of buying power and 28nm..no
U cant get lower if u buy ASIC, when u account everything in. This is rly cheep.
Wow... It's 4 more cents than 2.5 USD! Let's go ahead and spam and troll saying that it's expensive!
Seriously, please shut up. If you can't afford it and can't calculate when you will ROI, then don't buy. It's as simple as that.
If you think it's too expensive, buy hardware and suffer the electricity costs. Don't take the advantages of cloud mining.
