Cardano's proof of stake is liquid so you can stake and unstake at will. Also it is non custodial no matter what stake pool you stake to with a minimum stake of 1 Ada.
The proof of stake protocol is used to secure the protocol so you are essentially voting with your tokens what stake pool you want to secure the protocol, getting paid for it if your stake pool is picked, and incurring no risk of losing Ada when staking. Proof of stake is also at least 20,000 times more energy efficient than Bitcoin in practice.

Wrong look into CIP 1694 for Cardano. Also if anything is a security, it is Ethereum.
