Today I was educated again by "sandwich" trading: You think you're quick and lucky, rushing in to grab the deal, but it might just be you helping someone else cover their fees... Arbitrage, honestly, is more about seeing who can smell the opportunity first; being a half-beat late turns you into a background player. Recently, on-chain data tools and tagging systems have been criticized for lagging and potentially misleading, and I'm also a bit shaken: chasing after those pretty tags to catch trends might not be much better than blindly rushing in. Anyway, I now prefer to make fewer moves; I'd rather miss out than be the last to act. Well, what I don't regret is... at least I've started asking more before placing an order: whose "opportunity" is this really?
