They're giving away 20GH/s to new people who sign up, have open ended contracts, meaning they currently go until its no longer profitable or they decide to make them 1 year- 2 year. TH/S is only 130, which is extremely cheap to Hashflare, and the BTC withdrawl amount is 0.0001 which is extremely low. Two red flags do go off here and thats the low transfer fee, which would clog down the site once it got big, and the fact they're providing free GH/S. I put in 50$ and it has been reliable so far but want to hear what you all thing. Currently this is a steal for what its going for but has anyone else got any info on them? If you're interested check out my referral link, even if you don't buy anything registering, gives the person .10 to mining of your choice.
