I'm no longer pursuing explanations, but lately I keep feeling that: once the asset size increases, security becomes a matter of "whether you can sleep well or not." I can still tolerate using hot wallets for small amounts for convenience, but when it reaches a level where "losing it would cause a mental breakdown," hardware wallets at least move the signing step off-chain, which may be slower but keeps the mind clearer. Going further, multi-signature is more like adding a brake for yourself: one more confirmation reduces the chance of a slip-up, but management costs are also quite annoying, and when going out, you have to think about where your keys are. Restoring social trust sounds gentle, but honestly, it's about dispersing trust—if a friend/device/service provider drops the ball, it all has to be accounted for. Recently, AI agents and automated trading are being hyped up like crazy, and I feel anxious watching it: the more interactions are automated, the easier it is for people to outsource the "confirmation" process... For now, I prefer to earn a little less and pay more attention to the address during signing.
