Hi, i am using hashflare for 6 months and happy with their service. here, check my vid in December ...

if you would like to signup, all the links are in my profile.

happy mining!

My only concern is the price increasenron$2.20 per G/H

as long as bitcoin price is rising, there is nothing to worry about. you won't find cheaper price for th/s

I got in for a small amount until i can see it work for myself, once that happens i should look at buying more hash power.
