I like the initiative.

So if I understand correctly you don't convert them into fiat before donating and try to persuade charities to accept BTC?
What happens with the funds (BTC) when it takes to long for a company to accept them? Is there a refund after certain time period?
What happens with the funds in the meantime and why should we trust you?

Scanning through your FAQ, I think it would help if there is some kind of refund in case targets are not met. Then you have to gain my trust before I donate.
