Recently, I've been seeing everyone compare RWA, US Treasury yields, and various on-chain "yields" together, and I actually feel a bit guilty: no matter how detailed the calculations are, a single wallet security breach can wipe everything out. A mnemonic phrase is essentially a "highest privilege access pass," and my red line now is: no screenshots, no cloud storage, no sending chat records. If I can write it offline, I do. I keep copies in two places at home, and I’m too lazy to even dig them out. As for signature authorization, many phishing sites rely on you quickly clicking confirm. My habit is to close the page immediately if I see "unlimited authorization" or "unintelligible signature." I’d rather miss out than take the risk; if I really need to try a DApp, I use a small wallet first, revoke the permissions afterward. Anyway, a couple of extra clicks won’t hurt.
