Mining Cash Flow Line

Takes QUANDL Bitcoin blockchain difficulty data, three variables (hashrate in THs/sec, power consumption in kWh, and electricity costs in cents/kWh) and calculates the base line for cash flow in US dollars. The default is an AntMiner S15 at 10 cents/kWh.

When price is above this line, miners with the given conditions have positive cash flow (i.e. they make more money mining than their running costs), and when below the line, they would be better off turning their rigs off (if this simple model can be applied to their particular circumstance).

Assumptions:
1. All costs are consolidated into one "electricity cost" variable, including things like rent and wages for mining farms.
2. 12.5 BTC/block emission schedule (update source code upon next halving).

Warnings:
It is likely that actual costs to miners varies in complex ways. This indicator only shows a cash flow calculation for a very simple set of parameters that will generally apply to miners, but not necessarily all of them. (For example, a miner may be locked into a prepaid contract for cheap electricity, or sell exhaust heat in the winter for extra revenue.)
Positive cash flow is also different from ROI , as this model does not take into account the cost of acquiring an ASIC mining rig.

There is strong evidence to suggest Antminer S9 miners, the main arsenal for most miners in the past several years, are gradually being phased out. DYOR to find a good next-gen model's specs for more accurate results.

Dude, this is amazing. Thank you fro the share. May I ask though, if I were to use the QUANDL: ticker without s premium account, would the indicator still work?

As I understood, NASDAQ bought Quandl and it wasn’t possible to get Quandl data anymore. Am I wrong? (Obviously I’m wrong)

@chrysopoetics, I checked with a free account, QUANDL:BCHAIN/DIFF is available to free users. But you are right, some QUANDL data is premium only, but afaik their blockchain data is free. Please let me know if this isn't the case.

For some reason the chart shows the line for 10 cents/kWh while the code is 7 cents/kWh but both are correct.
Feel free to fork & make your own improved indicator :)

@kishin, I Modified one for LTC , Data is manual entry but it gets it on the chart.
TY
