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).
Yes, I am using the website's default preset. I don't know OP's electricity, and it's nowhere mentioned.
I did mention that the total profit will vary based on OP's electricity bill.
S21 Pros without electricity bill profit is also mentioned (Depending on when the profit is estimated considering the bitcoin price).
