Rly good post man. And kinda correct. I invested in PB , bought 5ghs with 0.051 btc, its been 3 months now and im almost even.
My experience is similar. Weekly return is about 8-10%. So, your buy is paid for in about 10-12 weeks. The other 4 years and 40 weeks is all profit.
If this wasn't profitable, people wouldn't be buying it. And, buying 30GHS for $76 for 5years at PBMinning is MUCH cheaper than the $299 for 1 year you pay at Cloudhashing.
BUt still it is a perfect setup for ponzi
. I just dont think it is.
