Is there any cryptocurrency that is stable at growth of 3% YBY

I am looking for a cryptocurrency that is decentralised and have a stable development. I think by using these 3 mechanism it would be possible.

1. Rebasing Mechanism: Some cryptocurrencies use a rebase mechanism, which automatically adjusts the supply of the currency to maintain its value relative to another asset or a basket of assets. If the value falls below the target, the supply decreases, and if it exceeds the target, the supply increases.
2. Algorithmic Stabilization: The cryptocurrency could use algorithms designed to automatically adjust supply to maintain a stable value increase. This might involve buying back tokens when prices fall or issuing more tokens when prices rise.
3. Backing with Stable Assets: The cryptocurrency could be backed by a reserve of assets that have a stable return, such as government bonds or other stable financial instruments that can ensure a return of approximately 3% per year.
