Lots of renowned ICO have done this in the past. This is nothing new, after all this is a presale not an ICO. We invest a lot of money into advertisement, if a community member can bring in better quality traffic then we don't see how that harms anyone for us to reward that person. This is to give everyone an equal chance. Seems like you haven't even read our fund distribution page in our whitepaper. There is a fixed amount of cash reserved for community bounties.
