WOW I left this forum some months ago, I am back and I see people still arguing the same stuff against PBMining. Truth is that this company has been up since the beginning and never failed a payment. If this is a Ponzi, it is the most customer support efficient Ponzi I have ever seen. Anyhow, people should stop bothering asking the same questions all the time. The owner of PBMining made it clear a loooooong time ago that he will not provide info on hardware, business strategy, etc.
I disagree. If pbmining was a ponzi they would have absolutely no problem lasting this long because they gained plenty of new customers to payout the few early birds and ROI is capped at ~5-10% profit unlike most ponzis which give huge compounded returns.
If pbmining is a legit mining operation then they are without a doubt the most efficient operation in the history of bitcoin mining. Even mega-scale mining operations with the cheapest electricity in the world cannot compete with PBmining and their free electricity generator.
It is quite an efficient and well executed ponzi, I'll give them that, but let's not kid anyone in to thinking it's a legit operation.
Just look at the evidence, there is literally none to suggest they are actually mining yet a never ending trail of red flags to suggest they are a ponzi.
PBmining is the only company that is completely fine with 90% of the bitcoin community thinking they are a scam.)
