I have a question about why are you selling %100 of the tokens. I can understand you are doing with good intentions but also after selling everything you won't need any motivation to complete the project. I think you should keep some of the tokens to yourself.
Actually I don't see any difference in if a project holds some tokens for themself or not. They get money through the ICO anyways, even if they would hold tokens and want to make an fast exit, they could just sell it and it's over. If they want to do a project, they don't need to hold coins for it themself, because our money will they get anyways.
imo thats the best if the people hold the tokens and not the devs. but on the other hand, there would be no need for the devs to go on further with the project, since they dont have any tokens more to sell, in case the price drops, and dont have to be scared to not get paid.
