I'm wondering about if Butterfly still worth to buy specially after Bitmain release the S5+ and S7 Antminers with low power, seriously i'm thinking of buying some boards of Butterfly which can mine with hashrate of 600-800 GH/S but i have no idea about how much will it costs me to buy 10 TH/S and can i use it all with just one Laptop ?
Feel free to tell me what do you think ?
well, point is that generally mining not worth the effort, risk and high dollars investments. simply because of electricity price, low bitcoin value, price of miners and raising diff.
there are imho only three ways how to mine with profit:
*you are in China next to power grid with direct contact to asic manufacturer.
*you are in US in some states with bloody cheap electricity (or you are stealing electricity) and you did some amazing aftermarket deal
*you are ASIC manufacturer
if anybody have idea about any other way how to ROI (and you see, I'm not even talking about profit), feel free to share..after some years of experience, I really don't see any other option:(
