I’ve an issue with calculations on the subject of cryptocurrency BTC, to be exact:

• manually calculate the estimated reward for mining.
• manually calculate the estimated vitality consumption.

For this process I’ve a file for a given miner, the place there are two columns:
date, amountBTC

Warning!!! under I’ll give the information I took for simpler presentation of the instance.
How can I manually estimate my mining reward based mostly solely on knowledge from the mine from the date, for instance, 2017-11-11 for 12 hours and for the quantity for this date, for instance, 0.005 BTC.
I’m new to the subject of cryptocurrencies, so please be understanding.
I do know that for such calculations I would like historic knowledge on BTC, which I discovered on this web site > hyperlink. (JSON knowledge).

At this second i discover some formulation:

amountBTC  = 0.005 BTC
networkHasrate = 6.86 EH/s (on day 2017-11-11)
numberOfBlock = 80 (on day 2017-11-11)
blockReward = 6.25 BTC
time = 12 h
PoolFee = 2%

myAward = (amountBTC / networkHasrate) * numberOfBlock * blockReward
myAward = (((0.005 / 6.86) * 80 * 6.25) / 2) * 0.98

GPUPower = 200W
GPUSpeed = 50 Mh/s

PowerConsumption = (myAward * 12 * 200) / (GPUSpeed * 1000)
 

I am undecided about formulation above.

I hope you possibly can assist me, I’m solely excited about calculations/formulation/features.
