Today, I'm going to talk about one of them namely BIT-X.com.
This website is legit and is more trustworthy then scrypt.cc. If you invest in it then you can make money via mining or just trade bitcoins to maximize your profits.
If you buy GHS for mining bitcoins then there is of course a cost for maintenance which will lower your income from the mining. If you think that the price of the bitcoins will go up or go down then you can either buy or sell your GHS.
It's all up to you!
