10/18/14: I am now 126% ROI for my bitcoin invested in gaw's bitcoin miners (actually scrypt hashlets)!!!  My plan at this point is to now build my mining power with future profits

Hello I started this thread to see IF and WHEN the gaw miners hashlets will ROI in terms of both USD and BTC.

I purchased a GAWMiner 1MH/s Hashlet on 8/21/14 for $15.99, which was BTC 0.030839 at the time with an estimated ROI of 52 days after fees.

Note: 8/21/14 is a partial day of mining and thus not a full days worth of mining payout

Each ROI calculation is done as if the miner was first mining on THAT day, so that I can track if there are any jumps in ROI times without averaging in past days.

Estimated Zen Solo Hashlet ROI time in days:

So currently the Zen Solo's cost 20.85 aka 0.0438 BTC for 1 MH/s. Each MH/s makes 0.00063617 BTC per day. Now if the zenpool payout per day stayed constant the machine would reach 100% ROI in 69 days. However, with difficulty increases of each coin and usually decreasing cost of altcoins the payout per day should be decreasing pretty quickly. HOWEVER, zenpool payouts on 8/21/14 were 0.00065055 BTC/MH/day and now its only declined to  0.00063617 BTC/Mh/day which is only a 2.3% decline over almost a full month! This intentionally does not account for the $0.08 fee per MH, which could increase in BTC amount if price goes up, or could become nearly no BTC fee if BTC price goes up as many people are projecting.

Lets extrapolate 2.3% decline in BTC for for the 69 day projected ROI and we get an estimated ROI time of 72 days (compounding decline).

Zen Primes will need to have some cool features added to them before I believe that this will be a clearly profitable hashlet to go with. The biggest thing they could add to these right now would be the ability to mine different algorithms as scrypt already has a LOT of competition and thus lower prices. With that being said, I also expect them to increase the price of the hashlet primes along if/when they ever add the other algorithms to them, because at that point they profitability will most likely increase quite nicely.
