I would agree to this on the following conditions:
1. they would have to tell us which exchange they intend to apply to and how much it will cost
2. make known the amount of money they have received in donations
3. provide proof of application once they have received what they need to list on the exchange
If I am going to donate towards a specific cause beyond what I have already invested, then I want to see proof that the money is going to go towards that cause and nothing else. I think that is reasonable.
