Maybe theoretically 1 AGT will be enough,but that wont make any sense,to stake such a low amunt as you would barely get any profit from that.
I aim at masternode,but for that a lot of AGT is needed.
Well, that may look like nothing, but that means that a lot of people will be able to stake and that is a good thing.
Of course,bigger the community,the better.And in general people like to stake, and since this will be POS system where you will get more profit every time you add more AGT, that will push price and value even more up.
