If we like it easy then bitcoin donation should be implemented, actually this is more transparent compared to fiat being donated as there is a bank secrecy law if it goes through the bank account and we can't track the cash movement, with bitcoin, we have the blockchain which is the public ledger which is easier to track when the amount is liquidated, more transparency would result to more people donating.
You can't track the financial transaction,but CIA can.

Every government investigation agency can ask the bank for financial information.Even if they don't ask,I'm pretty sure that CIA is currently spying every bank in the world,even Swiss banks.
more transparency would result to more people donating
I don't think that there's a clear correlation between having more transparency and more donations.
If the donator's private info is revealed,they will refuse to donate.
Tracking how the donated funds are spent is a good thing,but I don't think that the BTC blockchain will help for that.
