Currently the crowdsale sits at $21 million.
It is not rare, at all, for ICOs to quadruple or more their price. ETH probably 100x its initial ICO price or potentially more. Alongside a bitcoin bull market, there is probably a guarantee for Enjincoin to have at least $100 million in market cap.
Whether or not it goes to another level and gets into the $500 million+ is another question.
You are comparing one of the most successful icos of all time with a new ico, you are comparing apples and oranges, ETH is a project with many applications and enjin coins has a very limited use and that is going to limit the market cap that it can reach.
