Liquid staking and restaking
Liquid staking gives you a receipt for coins you staked with a provider. Restaking takes that receipt and pledges it again. Each layer is another way the money can fail.
The receipt
You do not hold the staked coins directly. You hold a token that claims them. The provider can be slashed, hacked, or simply big enough to matter to the whole chain.
Stacked again
Restaking uses the same security for extra jobs. Extra jobs mean extra ways to lose the stake. The receipt's receipt is not the original coin.
A point or an airdrop for restaking is often the only reason the extra risk felt worth it. Points are not the coin.
Check yourself
Is a liquid staking token the same as the coin you staked?
No. It is a claim on a provider, with extra failure modes.
After this you can count the layers between you and the original coin.
