What you guys think about Braiins approach of calculating the cost of production of 1 Bitcoin on their site? I see they end up mixing CAPEX with OPEX, but I can agree with the approach at least until we don't reach ROI.
The values are quite different from what I saw in the OP link.

They are still assuming free gear.

but they are accurate if your gear is free.

Most every calculator has fails

Think that their method is missing the cost to buy the gear..
think that their power price includes repairs, labor , infrastructure.

then they are accurate.

I like to add a penny or 2 to the power cost to cover all bs other than gear cost.

so if you have 3 cent power bill and a cent or 2 and your running cost is 4-5 cents.

that cover everything but the purchase price.

now 1000 ph is 10 s19's. cost is 4000 if you get them now times 10 = so 40k in the hole.

1000 ph of s19's burns 10 x 3.3kwatts or 33kwatts an hour or 792 k-watts a day lets say 800k-watts daily

at 5 cent complete run cost that is 40 usd
at 10 cent complete run cost that is 80 usd

1000 ph earns $93.80

so at 5 cent run cost you make 93.80-40 = $53.80
and at 10 cent run cost you make 93.80-80 = $13.80 a day

so both look like winners. well do not forget the 40,000 you spent for the gear.

so 40,000/53.80 = 743 days to pay the gear off and yet to earn any profit at 5 cent full run cost which is about 3 -4 cent power rest for things i mentioned above.

worse 40,000/13.80 = 2898 days to pay the gear = no good at all.

and that is top end gear grabbed cheaply with 3 cent to 4 cent power round up to 5 cents total run cost.

So right now mineing is terrible unless you have paid off gear.

the braiins site is not making that clear.
