Lunamine instead? Cheaper than Cex and they seem more legitimate than PBMining. BTW, PBMining has been great so far. Ponzi? I don't know but I've had no problems so far with PBMIning.


Full disclosure: I have contracts with PBMining and Lunamine. I'm 91% of positive ROI with PBMining on a 1200GHs contract. And I recently bought 2THs from Lunamine and I'm currently promoting them in my sig.
