I've been lurking in the group for a long time, and today I see everyone arguing again about privacy coins and mixing coins—whether it's considered "crossing the line." I can't help but chime in: no matter how much the compliance boundaries are torn apart, don't mess with the red lines of seed phrases and signature authorization... To put it simply, many "thefts" aren't due to advanced technology but because people left the door open. Don't screenshot your seed phrase, don't store it on the cloud, and don't send it to anyone; don't click confirm on pop-up windows for signatures/authorizations, especially those "airdrop/subsidy" pages—if the link even looks suspicious, treat it as phishing. Anyway, I always test with small amounts first, limit the authorization if possible, revoke it after use—it's a bit troublesome but gives peace of mind. If something seems too good to be true, I assume it's a bait.
