I have developed a project
https://github.com/peroksid90/crypto_calculator

to compare mining vs holding. Contributions and comments are welcome.

For example,
you have 2500 $.
You can buy a miner or just invest this money to BTC.
Which is better in the long run?



So at the end we see:

the worst case: do mining and sell mined profit every day (red line) (7300$)
the better: just buy and hold (olive line) (8200 $)
the best: do mining and don't sell. (magenta)  (12500 $)

magenta and red doesn't include the miner market price. So actually we should add it to the profit, because the equipment price is also rise(even used).
