In the past, I used to get overwhelmed hearing about blockchain builders and bundles, feeling like retail investors were miles apart; now I think it's enough to just know what is "sufficient": the transaction you send may not be included in the block at the moment you click, it could be bundled, front-run, or reordered... Basically, don’t take "I clicked = immediate execution" as gospel. I usually remember three things: try to use reliable wallets/routes, don’t click on unfamiliar links randomly; don’t push large amounts during congestion, split transactions + set limits/slippage to avoid too much risk; if you see strange transaction prices, suspect that you’ve been front-run. Recently, hardware wallets are out of stock, and there are tons of phishing links again. I used to think security was a hassle, but now I really can’t slack off—anyway, surviving first, then talking about interactions.
