I do not understand why people do not care about this. It is a good indicator if the price for a token in a pre-sale is not over-rated. I give you an example, 1 token is sold for 1USD in a token sale, there are 1 billion tokens in supply, to reach this price after a token sale, the total market cap has to be 1 billion USD, that is more than NEO or VeChain market cap - so as you can see, it doesn´t make a sense and probably it is not profitable for you.
