Digital cash you can feel good about
Digital, lockable, paper-optional
Printable, tradeable, unique artistic crypto-tokens with face values
Swap your fiat for them by giving fiat to a nonprofit charity of your choice
Get face value tokens 1:1 with 2021 U.S. dollars
Supply is naturally limited by how much people can afford to give to charities
So give $10 dollars and get a $10GC token. Or maybe you get two fives. Or a five and five ones. Same difference. It's digital cash.
Each denomination has personality! Instead of Lincoln, Washington, Hamilton, states, or Queen Elizabeth, you can get Pennzy, Billy, Centaur, and a whole family of characters.
Each individual token permanently lists the particular charity it was "born to help."
Keep a digital wallet or print your tokens to use as paper money. The owner can lock and unlock printed tokens by scanning their QR codes. Unlock printed tokens before you hand them to someone else. Scan tokens you receive to confirm they are unlocked. You can sweep any unlocked tokens into your own account, locking them to yourself and letting them automatically show up in your digital wallet.
Specific nonprofits may offer special-edition tokens, still with the same character for each face value but created and signed by artists or celebrities and issued to any desired degree of scarcity.
Most major stores of value are not "redeemable" - USD, euros, gold bricks, Bitcoin etc). But if redeemability matters to you, then when you get new GC tokens, you can buy a "money-back guarantee" to return/redeem GC.
