Allow me to introduce a new form of decentralized currency - JoyCoin!
Mining:
Everyone can mine JoyCoin everywhere they are by doing things that bring them joy!
Spending:
You can share your JoyCoins with others and teach them that they can mine it too!
Demurrage:
Your joy-wealth decreases if you are not following your joy, thus hoarding is prevented!
Decentralization:
There is no single central authority to define joy, everyone will have to figure it out on their own.
System integrity:
Your joy-wealth is destroyed if you prevent others from generating or sharing joy.
There is no premine, the amount is unlimited and infinitely divisible.
Let the mining commence now!
