PBmining for all of life, I love it. Because cex.io have more price changes than pb mining, so I think that this is more stable than cex.io. It is not a case that I've signature of pbmining 
CEX.IO with fees and maintenance costs is very expensive but in any moment you can sell GHS - this point is very good. PBmining is probably the cheapest on market: price 0.0015 / GHS - and that is what people are looking for.
Ps. If someone decide to invest in PBmining - PM me, i will tell you how to get 5% more power for free
PBmining is no more the cheapest. It was so a few days back. Now it is 0.0021 BTC/GHS. Verify it @ pbmining.com. It seems www.cloudmining.website has the lowest offer at the moment. It is 0.001 BTC/GHS.
Sent the cloudmining.website guys 0.01 to try it out. If it flops I´ve given mere chicken feed to petty thieves, LOL.
