He has a point though, 1.5 Billion for something that doesn't have anything to show for is ridiculous. But its the nature of this market that this works as everyone is heavily speculating and prices shoot up and crash down. So it can still be profitable ''investing'' but thats with every token/project, they all promise the world to you but seldom deliver.
Look at us talking about billion dollar valuations like they are nothing. Just last year to be in the top 100 at the beginning of the year you needed a 1m whereas now you need 129m at time of writing. Obviously we can't make another astronimcal leap like that but I could certainly foresee the #100 spot needing at minimum 500m by the start of next year.
