Look at the marketcap of Ethereum. It's at $1B. Synereo is much better than Ethereum from a technological point of view. Synereo is also much more marketable than Ethereum. Even if Synereo just reaches $1B marketcap in two years (personally, I think it will go much higher, much sooner), you're looking at a total of 223.33M AMPs with a total market cap of $1B which means each AMP would be worth $4.47 USD.
Lets keep things realistic , 4 dollars would be amazing but i would already be happy with a 1 to 2 dollars price
