Asicminervalue is showing an estimated profit of '$14.18' daily for Antminer S21 Pro.
The estimated cost of electricity per day's use is '$8.47' - Electricity cost isn't mentioned, so this value varies depending on your electricity cost.
The total estimated profit will be $5.71.
ASICs are expensive, and the stock gets sold more quickly than GPUs. At eBay, sellers usually sell used ASICs cheaply, but I wouldn't go that route.
This is wrong and misleading. You need to configure the OP's electric cost in order to get an 'accurate' approximation from Asicminervalue. You are either using the website default setting (or one specific to you).
Typical power rate in Ireland is 0.34 Euros / €0.34.
S21 Pro uses 3500w or 3.5kW. 3.5 kW x 24 = 84 units per day.
84 x €0.34 = €28.56 daily cost to run.
Asicminervalue earnings figure for S21 Pro = $14.12 (USD) which is €13.55 euro
So... €28.56 running cost, €13.55 earnings = MASSIVE LOSS
