I think this will be a great solution for those who are engaged in charity. All the inconveniences that could arise when using a fiat currency, are minimized, or completely disappear. In the real world, there are a lot of fictitious companies that pretend to be doing charity.
This project will help interested people to really help the needy, and not give money to the liars. I think with good presentation, the project will succeed, and will be able to interest many people, even from those who have never done charity.
I want to wish good luck in achieving your goal.
