For exemple i have electricity at 0.07 USD/kwh.
Is it worth it to buy some S21 XP or other new miners ?
if you get the s21 pro for 4500-4800 usd lets do math.
234th
3510 watts at 7 cents
or 234 x 0.0475 = $11.11 usd in coin
3.6 kwatts x 24 = 86.4 kwatts round up to 90 kwatts at 7 cents or $6.30
so $11.11- 6.30 = $4.81 a day profit. you will be close to even in 1000 days.
it is an if a maybe.
The question is how many can you run?
do you have power for 1 or 2 or 20?
If you can run 2
I would buy 1 and run it I would also buy 4800 in btc.
After time see what the better move was.
if you can run 20 at that price it is very risky.
Also the xp is much too much money to buy at this moment. plus you have to wait to get it.
