Recently, I saw someone discussing the "compound yield" of re-staking/sharing security.

Arguing back and forth, I didn't really care much about the returns; just focus on keeping your wallet safe...
Don't screenshot your seed phrase or upload it to the cloud. If you really need to memorize it, make two offline copies and store them separately.
Don't rush to click confirm on signature authorizations, especially on pages that say "Upgrade to claim/verify assets," which are basically phishing for unlimited authorization.
If you can use a secondary account, use a secondary account; only use your main account for transfers and avoid overly complicated interactions.
I'm not regretful about the outcome, but about thinking "just sign once, it should be fine" at the time.
The only red lines are: keep your seed phrase offline, and don't sign on unfamiliar sites.
That's all for now.
