Excuse my provocative title
I am finding that except for a narrow range of BTC price rise, it is better to buy BTC than to mine it.
I have been looking at buying Antminer S19j Pro 100 TH (3250W) from compassmining using their hosting ($.0624/kWH) and F2 pool (1.2%)
It costs 8000 (after 3% credit card fee).
Assuming a starting BTC price of $30,000, with starting difficulty at 1.4363, with both increasing at 4.4% per month:
After 3 years:
- ROI of mining - 181%
- ROI of purchasing BTC - 351%
Change the BTC price rising to 6.5% per month, which corresponds to BTC doubling every year:
- ROI of mining - 337%
- ROI of purchasing BTC - 806%
If BTC rises only 1% per month, then the ROI of each about the same.
- ROI of mining - 40%
- ROI of purchasing BTC - 42%
At less than 1% rise per month, mining does better than purchasing.
So, you can't mine BTC profitably at current miner prices and hosting fees at compassmining.
Prove me wrong!
