I want to say that many people are trying to calculate profit from ASICs that are not yet for sale.
Perhaps if you receive this ASIC one of the first, then the first month the profit will be the same as in the calculator.
But then, as ASICs are sent to many buyers and start mining, the profit will quickly fall.
the L7 should let us know what is in store for asics the next five-seven months
ie if it comes on time and the diff jumps 30% cool
but if it comes a month late and diff jumps 65% not cool
we have no idea how many they will release but in 2018 gear flooded the market and prices tanked liked a mofo.
if gear is restricted and diff does not go crazy then i think we are in good shape.
