These are hardcore Aavegotchis meant for the most responsible and insane riskers. You put a lot of money in it and hope to 100x it or get liquidated. You have to take care of your Aavegotchi's collateral risk or it gets liquidated. Only the most talented Aavegotchi caretakers manage to not kill these Aavegotchis in less than a day, let alone an entire year. You're taking care of a ticking time bomb in full traffic just like trading futures on 100x. Fear an old Aavegotchi in a profession where many die young.
As usual it's up to a real game designer/economy expert to actually make sense of this.
