I would love to know what is the most accurate sites to calculate bitcoin mining profit.
I have checked may sites and enter same numbers yet profit does not match.
For example for s9 I enter following information.Since halving is close I calculate the reward as 12.5
According to coin warz
Hash Rate : 12900
Power Cost:0.10 cents
Power:1275 W+10%=
Pool fees: 2%
Block Reward: 12.5
Hardware cost: 2100+ power supply+ shipping to Canada=Around 2700 usd
Bitcoin price:670 usd
My profit after 1 year:2817 usd
If difficulty stay same or increase little, and bitcoin price stay same I will be break even after a year.
Let me know if Iam making a mistake or forgetting something else to include.
Coinwarz is good for current period is about it, you can't really easily change difficulty so that makes it harder for future mining profits unless you take the numbers to excel or something. I would suggest taking a look at -
https://bitcoinwisdom.com/bitcoin/calculator . It's going to have a lot more you can enter in getting more accurate info on cost's and what percentage change will do.
There is still speculation as part of it though as we will never be able to say know the next month or two will do on difficulty or price. So more accurate yes. But perfect no due to having to use speculation.
