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.
