Last night I almost accidentally used my main wallet to claim an "airdrop," but luckily I checked the domain name first, and it looked exactly like the real one... To put it simply, a mnemonic phrase is like a combination of a bank card password + ID card; anything that prompts you to input it is a red line. I’d rather miss out than take the risk. Also, don’t find signing authorization troublesome—when I see ones with "unlimited limit / long-term validity," I usually just refuse or give the minimum limit, then revoke the authorization after use. Anyway, clicking a couple more times is better than zeroing out later. Recently, there's been a debate in the group about privacy coins, coin mixing, and compliance boundaries. I don’t really have a stance, but at least for safety, don’t make yourself a source of "suspicious fund flows." Use separate accounts for clean funds to feel more at ease. That’s all for now.
