is
https://bitcoinwisdom.com/bitcoin/calculator a good place to calculate ROI? i keep messing with this thing and still cant find ROI.....everytime i do it im in the hole $700+ after 200+ days. these things need to be cheaper. and with the reliability issues of late, i think im better off just buying a bunch of btc and seeing if it increases in value over those 200 days...when stuff lasts 2 weeks and burns up or fails..... that means it is total crap!
I'm curious... Does your electricity rate per kWh need to be cheaper?
5.9 cents a KW. which is low for most of the USA....
And you can't see ROI?
Can you not see future price of bitcoin going up considerably just before the block halving?
Of course, I have plans on moving soon to an area with $0.0285 to $0.0325 per kWh. That's the main reason I'm loading up on rigs. However, I'm not moving until I have 200+ S7's. It could be end of July [After block halving] or it could be the last quarter of 2016. It depends on how certain things play out as to the timing of my move.
you are probably talking about S7 hypothetically, but I don't see it being a good large scale investment by summer, although with low electricity cost, who knows. I am pretty sure we will have at least 0.1-0.15J/Gh machines by then (S9?)
One thing is clear: unless speed of diff rises significantly decreases, buying btc directly would be more productive with zero overhang and maintenance cost.
