These past couple of days, I've seen a bunch of people arguing about "data availability / ordering / finality," and the more nouns there are, the easier it is to get overwhelmed... I’ll focus on one main thread: the final say on the order you placed, the candlestick you see, how long it takes to be finalized, and whether it can be reversed afterward. In simple terms, it’s about "can it be verified," "who is in line," and "can it be reversed or not."

Last week, I almost got carried away by emotional trading during perpetual contracts; upon review, I realized it wasn’t that I saw the wrong direction, but that I took "already confirmed" as "absolutely will not rollback," and I’ve fallen into this trap for the third time.
By the way, the debate over privacy coins / mixing coins and their compliance boundaries is also quite divisive, but it all circles back to the same point: if you want more privacy, you have to accept harder proof and more difficulty in accountability; if you want more compliance, you have to accept more transparency and more rules. Anyway, I’ll keep my positions in check first and not let the terminology cut my hands off.
