What would be the purpose of dividing adoption-squared by number of coins? I don't see how that is useful.
This is basic. Imagine that the number of coins doubles. Then the price is divided by two.
Therefore the objective price is inversely proportional to the number of coins in existence. Any model for price should take this into account. Indeed, one could only consider the number of coins that are not lost, but the estimates on these differ.
This will give a small correction to your formula, that may be irrelevant now but not in 1 or 2 years.
