Even so, the math I just did indicated a 232 day payback for my Batch 1s. Of course, that is optimistic since it presumes today's difficulty for the entire time.
It's more than that even, it is unrealistic because the block reward halving will occur prior to your already optimistic estimate of 232 days, and that's going to throw a whole box of monkey wrenches into the works.
The only people that will net profit from the S7 is Bitmain.
I think a lot of people did optomistic ROI math on this machine, specifically batch 1. I am not sure they will make ROI by having. Unless BTC goes up in value a good amount, and you are using money not BTC as the indicator.
But we have a LOT more of these miners to come. One thing that might save a lot is mining till having and selling. I predict even at having it still holds a decent value.
BTC is like gold.
If the dollar becomes less attractive gold goes up, BTC goes up in terms of dollars.
BTC is like the gold off digital money. Not like gold. Gold will forever retain a value and is a safer bet then BTC. BTC is more risky and we really don't have a long history to compare it to.
I don't know how much effect fiat money "becomes less attractive" translates into BTC investments. I think BTC is still young and has not reached this point for majority of people.
Gold is a bit different because they kind of printing press it, there is only one physical gold ounce to about 250 ETF claims on it.
Can't ETF BTC. very nice.
