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.
Well, for me it would feel still a little better if i would hold some of my projects tokens since ICO money should mainly go for development and advertisements to assure a good start.
