Your offering S7's at 4.73TH/s, at 380USD.
whats the exact cost of hosting for an S7 per month with you? about 60$ a month? (40$ per kw and they use about 1.3) if so that leaves about 35$ profit a month granting no diff changes (assumed to be another 5+% in 3 days) . that profit margin is SLIM, and on 28nm ASICs :/
thats 11+ month ROI with NO dif changes if they bring in 35$ a month after hosting fees and cost 380$ :/
ouch, no way personally.
Let me guess,
1. your assumption is based on today's btc price and it would not go up in the future. Yes I am biased that btc will go up imho or else I would not bother messing up with all these.
2. you've assumed this purchase of hardware as a sunk cost at time zero, which is not exactly true. Should something happens to one's daily profitability, the hardware would, likely, still bear a residue value. Back in September 2016, S7's were sold for around $250 or less, just for your reference.
Otherwise, your math is right, no argument here. I believe I have put up all the sales related info as reasonably much as I can. Good for you if you could be better off elsewhere but not everyone could enjoy what you have.
true, 2 valid points, cant argue there! the residual value will STILL prob be 200ish even in a year, i would say, so that IS a factor, yes.
and i agree, BTC only really goes up long term, its almost safe to say this time next year it should be easily 1500USD+.
As a long term proposition these could be a great investment for sure, and if in a DC you will be there to admin them so thats valuable too.
Best of luck!
i may actually go in on one myself as a long term hobby miner i can sell at anytime
