Haha. For something so far-fetched, it's hard to say that it will. A billion in ICO is quite unlikely (not saying it couldn't happen). Right now its valuation is around 1.5 billion dollars, considering of course, that it would keep growing at the rate that it's going now.
Only 20% of the tokens are to be released right now. If the HYPE continuous to outpace the distribution of tokens, you could see prices going up (Which is what mostly everyone is in for). Now is that likely? I'm not sure bud.
BUT, if this system gains traction faster that zcash or ethereum (meaning partnerships set up, any necessary infrastructure deployed quickly, early adoption of businesses), we might see prices explode. So at the end of the day, yea, maybe you're right.
