As a short-term trader, I find the "credibility" of projects to be pretty basic: first, check GitHub to see if someone is actually working on it recently, not just submitting changes to README; then glance at the audit report, the focus isn't on how professional it looks, but whether it clearly states "which parts haven't been audited / what risks still remain," and whether the team has responded or fixed issues. Upgrading multi-signature wallets is the same, don't just trust "multi-signature" when you hear it, who are the signers, what are the thresholds, can they be replaced unilaterally—that's the real concern... Basically, don't mistake "having documentation" for "being safe." Recently, that main public chain upgraded and went offline, everyone in the group is guessing whether the ecosystem will migrate, but I think it's more realistic to watch how the project communicates and updates its code during such times than to guess the direction. Anyway, I’ve set my stop-loss first, don’t get too emotional.
