I actually mine with a rival of yours, I must tell you, if you reinvest 25% of your proceeds in the hardware I would say you are not going anywhere, I mean it takes about 15 months to break even on average, and then you have another say 8 months or 10 with earnings then you need to replace the hardware. Sure there are better months, but since the whole industry becomes larger it is to be assumed that profits will be less. So with 25% of proceeds, IMHO, there is no way to replace the rigs.
Also can someone please tell me if the company really believes that there is a 161% ROI for the investor, that reminds me the example with the king and the beggar and the rice, in no time every investor would have more money as there is money in the whole world...
