You make a point, after the first 200,000,000 tokens are given out on those 5 days - the market cap is the token price * a billion. Token prices over a dollar equal a market cap higher than a billion. I don't think it is unreasonable to say that some of those won't be tradeing for 30+ dollars. That puts it on par with ETH market cap.
After those 5 days and the hype is at all time highs, it will be interesting to see how the price deals with 80% inflation over the course of a year.
I am not sure.
