No just stay away from Ghash.io they are the biggest unethical pool I have ev r seen. i have compared their cloud to a lot of other cloud pools I compared my end result BTC from my machines witrh a lot more mining pools. In the end at the end of the day Ghash.io makes more in profit from its pool members. they flood you with numbers and statistics to make you feel like you reall are earning, its not until you go out and look around that you really se how unethical this mining pool really is.

Even now I have a 3 month ROI on the machines I buy. I have a system I put together and I work my machines to do this, but it can be done even with BTC prices at their medium levels. Its not easy and some days are way better than others, but it still can be done Just know GHASH.io is not one of the pools I use to do this as their profit taking is larger than their pool members can ever get. if you mine with Ghash.io your ROI will be 8 months on machines you own, and 16 months or more on your cloud there. Most of the other top 10 pools uder them (discuss fish being one) will get you and ROI in about 6 to 7 months, and if you do what I do with your machines you will get 3 to 4 months ROI. Its all about what you do when you do it and how you do it.
