These days, I see everyone guessing whether the ecosystem will move before or after a major public chain upgrade/hard fork.

My first reaction isn't "opportunity," but "is the confirmation count enough"... After experiencing rollbacks and stuck blocks, it becomes about finality.

AI agents can really click around for people, but I think there are still a few things in on-chain interactions that need human oversight: the moment before signing (who are you authorizing, is it unlimited authorization), the cross-chain/bridge step (if the path is complicated, I assume there are pitfalls), and the upgrade window (RPC issues, block production rhythm changing, agents will just run as planned).
In short, they can execute, but it's hard for them to bear the consequences if "this transaction gets stuck/reorganized."

My own way to avoid impulsive trades is pretty simple: any operation that requires a signature is set aside first, and I wait two or three blocks before checking again; when I want to chase, I first reduce the amount or just observe without opening a new position.
Anyway, if I miss out, I miss out—staying alive is the most important.
