1. High rate of return - Tick for PBMining

pbmining doesn't meet your #1 point... high rate of return imo would be prices lower then buying a miner yourself and/or higher payouts per GH/s neither which are true.   $5 per gh/s isn't a deal really and what I would probably expect from a reseller/host type business.

For the rest no comment because I have no direction knowledge.  Could very well be a ponzi...


$5 per gh/s imo does not offer the returns worthy of investment, not nearly worth the risk with a new company which has not been 100% transparent.
