for me it is the single reason for staying with cexio and that's the equipment being maintained by them, buying equipment is very expensive now and you don't see an ROI for a long time, by which time the difficulty is always increasing.
Are you saying that if you use equipment maintained by them, the difficulty rise wont affect you?
I dont understand on what basis do people buy GH/s on cex.io. 1 GH/s bought today at cex.io will make a total of ~0.01 BTC in its lifetime (assuming 30% difficulty jumps) and from mid may will actually start costing more in maintenance fee than it would mine.
I have a feeling that they artificially inflate prices to make people think that their GH/s is actually worth something. One day when people get better at math, it'll come crashing down. Hope you aren't still holding your GH/s on that day.
