Yeah, where are you going to get funds for all of your expenses? Most project promises 100% on their investors but then it turns out they can't so near the ending they change it to 80% - 90%.
This is a charity work I know, but please let's be real.
Obviously they take the funds for their expenses through the donations.
The amount they do not use is called the "profit" and distributed.
That is why I'm asking about their expenses.

Oh okay. thank you for clarifying
I thought this was like most ICOs. So you are asking how many percentages from the donation their going to use for expenses.
