During the subsidization of ICOs by Cobinhood, the people that have the tokens are at an advantage of obtaining cheaper ICO tokens compared to the usual ICO partaker. The icing to the cake on this is that Cobinhood token holders may get very low rates.
It's quite a bit better than that, at least for their first ICO, Cybermiles (CMT). COB holders received free CMT tokens, before the ICO even began. Participating early in an ICO often gives one a chance to get in at a very low price. But free is a very good entry price indeed!
I have been looking for information about whether Cobinhood plans to do this for all future ICOs, or if this was just a one-time thing they arranged with the first ICO. If its for all ICOs, it is worth stock-piling as many COBs as you can.
