5 billion is too high. and the problem would be if you invest your money in it and then the market reacts negatively with it the price could go down. I would better invest in Ethereum today It is priced at $303. and was at $375 a week ago, 25% win even long term is better than 5% lose short term.
I advise everyone to wait until the coin is in the market.
anther thing is that personally i wont invest my money on a coin that is available only in one exchange, this is very very risky.
