My current general conclusion is: don't be scared by words like "data availability / ordering / finality." Basically, focus on one thing—whether the order you placed or the coins you transferred can ultimately be seen by everyone, recorded in the same sequence, and unchangeable. Data that can't be seen = no one can review it afterward; unstable ordering = the same transaction might be reversed or reordered, and you might think it’s completed when it’s actually been front-run; slow finality = inventory and pending orders are always in a "semi-confirmed" state, which can easily cause anxiety. For someone like me with small funds practicing order placement, I prefer to earn less but keep my curve smoother, so I pay more attention to "adding positions or placing additional orders only after confirmation." Also, recently hardware wallets have been out of stock, and phishing links are everywhere. During chaotic times, don’t rush to click links or sign transactions. Confirm first, then operate—avoiding a slip-up is better than making an extra trade.
