quote the part where i complained about bitmain ? mining WAS not like any other business, I roied on some Asics in under 2 months, what other business can do that? not even drug dealers can do that ! .
plus you ignored the real question which is how do you calculate profit for mining? i answered for you but you are just refusing to admit it. ok so let us keep this plain simple, you told us your power rate 5.5 cents. and we will be able to tell exactly how much will it cost you to buy the S15. and we will assume those miners you getting are A+ quality that will last 10 years . why don't you prove everyone wrong and come back when you get your ROI ?
i am betting "whatever amount you willing to bet" that you will never make it. bitmain is feeding of noobs like you and that's pretty much the only thing that keeps them going , noobs who pay close to 200$ for shipping plus 25% tarrif fees and with high power rate try to compete in the mining market.
so prove me wrong and come back when you ROI. other than this whatever you say is just B.S like everything else you said.
