In fact, i'm good at math. I have a proof of daily payout on my blog since 15th september or so...with screenshots and I can say its very profitable.
No contract, you can sell your Hashlets when you want so... I cannot say how it could affect bitcoin price, I think someone who buy for one or 2 million of mining rigs will still have an impact on bitcoin price, you tell me.
With the Zen Hashlets and the Prime Hashlets, we mine on Zenpool, its exclusive at GAWMiners and we can still mine in Altcoin, not only bitcoins. I always suggest to buy only theses one at the moment and..I can say my rates is ok, Zen Hashlet got a ROI of 130-140 days.
Certainly, tricking people into believing they are going to make money hashing can be profitable if you make money with affiliate revenue, but that isn't exactly ethical is it? Can you humor us with your math proving 130 day ROI? Even if you ignored history and assumed a 0% difficulty increase you will still never make a return on investment with the 447.50 GAWMiners Hashlet.
Here is a tool if you need help with your math ---

Yes there are a lot of Hashlets...Yes some have a ROI of 220 days, that's why I only recommend Zen Hashlets and Prime Hashlets at the moment.
All the daily rates of Zenpool are on my blog and you can notice its stable at ; 0.00061014 BTC / MH
A fan on Hashtalk made this spreadsheet ;
http://gawminersaffiliate.blogspot.ca/2014/09/roi-calculator-sheet.htmlI dont recommend Clever, Waffle and Multi cause the ROI is not good and the pools rates vary a lot.
Zen Hashlet is stable and its the one I use most.
I don't have a lot of Primes even if GAWMiners say its futureproof and have some features. I'm waiting for the tonight or tomorrow announcement and for the Project Prime before investing in some more Primes Hashlet.
So if you go with Zen, yes its possible...Like anything you want the best for your money, so did I.
