The project is great but how much we can expect to grow this one ? cap at 3 bln for 1$ ? Well , let's say we are in December 2018 , total market cap at 1 trillion in that case, yes I can see Iota going to the moon maybe stopping at 50 bln market cap max which means 20x from now. The other possibility is to iota competing with BTC (not really realistic) and in case if we go to 200 bln then this will be equal to what some alts like Monacoin already achieved .
