Sorry, but I am still not quite getting this. So all coins are in existance. Sop we still have POS. So we can set up an online active wallet on our PC, which is a master node and we get coins for this. So what are we actually doing here?
Facebook was never really the place I saw ICO adverts. I think it is too generalist there for much effect. I suspect this action is for when Cryptos become mainstream and then they can keep the frenzied posting down then!
