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.
Nice, it's nice to know that we can invest as low as 0.1 eth in this ico. with this, I am sure that many investors will be attracted to participate.
