haha given cex's prices I think it is not too difficult!
If it's not too difficult, can you offer what cex.io does TODAY? With March 1 hashing start date and limited or no ability to sell your shares in 3-4 months, I would never ROI with your offer.
Bash CEX all you want, they are extremely competitive at this time. I ROId 6 times in 2 week increments. I also participate in DZMC group buys who are yet to ROI but there is some hope there, most likely will barely break even for my 15/16 involvement.
Sorry.
You are just trading with gh/s on cex and maybe you got some profit, I was talking just about price of gh on cex that's higher than mine. We're going to mine not to trade
