How about after we finish the physical trust chain, we initiate a digital one? Maybe with some digital collectibles?
Why not run both in parallel? You could create a simple ERC721 token that can be passed from person to person.
Reach out to crypto-collectible games like cryptokitties and others to see if you can make the token have some special functionality in their games.
Every time the collectible gets passed around it should gain in value, then you can sell the ERC721 token to a final bidder, and release the gathered funds to charity for a double whammy donation.
