Recently, someone asked me again whether staking/sharing security is really worth it.

Honestly, earning multiple yields is fine, but don’t take “security stacking” as a default setting…
The underlying trust you stake out is actually being transferred multiple times; the longer the chain, the more it looks like hallucination stacking.

Especially these days, with cross-chain bridges having issues again and oracles reporting errors, everyone’s consensus to “wait for confirmation” makes me more cautious:
If any link in the chain gets stuck or broken through, the subsequent yields might all disappear, or you might think you can withdraw at any time, only to find liquidity has shrunk into the corner and isn’t moving.

My own quick fix now is: better to earn less than to clearly understand who’s responsible if things go wrong, how to stop, and how to redeem.
Don’t get carried away—play it safe.
