Yes, this is the reason why a lot of people now are joining this project and I hope they already invested good amount so that they will have high chance of huge profit very soon.
What is the minimum amount of investment? I would like to invest in the project, but I worry that my investment will not be enough
Minimum purchase is 50 AST tokens. Get a bonus from 10% to 25% on every token purchase. And at Stage one of All-Stock PreSale, the price is 1ETH = 625AST -> Min = 0.08 ETH. For make sure, you can make investment with at least 0.1 ETH.
