Recently, we've been discussing on-chain privacy. Honestly, I don't have any illusions about being "completely anonymous," especially once you get involved with fiat on-ramps and off-ramps—the compliance boundaries are right there... Ordinary users can only avoid posting addresses like social media updates, avoid clicking on unknown signatures, and try to fragment their on-chain activities as much as possible. As for cross-chain, I still stick to my old habit: small amounts, multiple tests. Better to take it slow than to rush into unfamiliar bridges all at once. A friend also asked me if earning points on testnets means "mainnet will definitely issue tokens." I can only say, don't treat privacy as a shield, and don't see points as wages. If you're really participating, just treat it as product testing—play if you can afford to lose. That's all for now.
