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?
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.
1. That is correct, we will only pay out to organisations that officially state that they accept bitcoins, until then we will accumulate until they cant say "No thanks" anymore.
2. See FAQ 11: What happens if an organisation never starts to accept bitcoins?
We have discussed refunds, and we might change our minds, we gladly listen to input. However, for now, the plan is to cover the fees for other charity targets with the funds of abandoned donation targets. This can be done automatically fairly easy and it will put all the funds back into charity without extra fees.
