Straight up, how am I supposed to invest in this when you are pre-mining to  "donate to charity".  It makes no sense.  In your mind it is probably attractive to people and they will think that you are a good guy for wanting to help others.  That is fine and being charitable is a good thing but this is such an inefficient way to be charitable it comes off as a ploy rather than an actual initiative. 

Drop the premine and I will consider participating.

Good luck with your project.
