Why do people pay .020+ BTC to earn .015 BTC???
what do you mean?
I dont use the above contracts. I picked up some at gaw actually picked up a 13mhs blackwidow with free 1 month hosting about 1.5 months back. Yesterday I converted them to hashlets which were prime hashlets. I have about 80 usd in my account at current rates. And if I sell my primes I get back 80% of the value of the current primes which is 50 usd so I get about 40 usd per prime. If I sell I get back $520 plus the 80 bucks I have for hardware that I paid $221.
The primes are amazing though. I mean I can use them on 2 pools at the same time and get payout from both pools(12hour on one pool and 24hour on the other pool) Then there is a boost feature which I think gives you 50% boost for 30 mins and there are other features soon to come to primes. So I do suggest using gaw to pick up hashlets as the best way to go if you are concerned with ROI. They do have alot of bugs but they let the community vote on things they plan to do. Tell me of one service that allows that. And they are very active.
