Someone commented to me, "Aren't you studying token models? Why do you keep mentioning security"… Honestly, no matter how refined the model is, if the mnemonic phrase is lost or signed incorrectly, everything is wiped out. My three red lines are: never put mnemonic phrases into any web pages or cloud drives, screenshots are also not allowed; if you don't understand the signature/authorization, don't click, especially those "free claim" or "wallet upgrade" ones; if authorization can be used once, don't give unlimited access, anyway, canceling a few extra clicks isn't tiring. Recently, everyone has been complaining that validators earn MEV and that the ordering is unfair, I’m annoyed too, but retail investors can mainly control that one "confirmation" themselves. That's all for now.
