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.
How many Agate tokens is needed to run your own masternode and when will that go live?
Everything will go live after the ICO ends, when main net is released alongside the app and wallet.
