Besides we know who the guy is, i dont think someone that is so open about his ID and company details is that stupid to scam us.
You think he was open about who he was? He's lied about his name for a year and done everything he could to obfuscate the origins of the business. The only reason his name came out is that the business registration shows Jason Boyko registered the forerunner to PBMining as a sole proprietorship. The Jeremy Biggs alias was a fabrication.
How about this:
PBM 1000 = skimming
Genesis Mining 1000 = just because
AMHASH1 800 = that´s how it is
Hashie 750 = high electricity costs
GAW 700 = you dumbass don´t get it
The companies there disclose their mining fees when you sign up for the service. PBMining on the other hand has always maintained that they pay out exactly what a calculator says your hashing power should pay. While they deleted the references off their site and claim they changed it shortly after posting the formula in January, even up to the middle of August they were claiming that they take no cut and if there appeared to be a cut from the calculator estimations it was an error in your math.
Not true at all. If you compare our payouts from the last few weeks to calculator estimations, you will find that our pay every week is always less than estimations. A cut is taken there.
All estimated costs are worked into the purchase price. If there appears to be a cut, then there was a problem with the observers math somewhere.
Remember to factor in the fact that the payout is not always at the same time every week. This will make it fluctuate between appearing inflated/deflated.
Saying we charge X per GH/s with a $Y/day/GH/s maintenance fee and then doing it = acceptable. Might not be a good investment, but there's nothing wrong with it.
Saying we charge A per GH/s with no fees, all electricity and pool fees are built into A and then claiming A-B=C is not acceptable.
