Lately I keep seeing a bunch of terms like "data availability / ordering / finality," which sound like exam topics, but really you just need to follow one thread: whether the content of your transaction can be accessed by others, whether the order can be manipulated by someone inserting transactions, and finally whether it can be overturned the next day. Basically, if the data is visible but the chain doesn't recognize it, it's useless; if the chain recognizes it but the order is jumbled, the experience is like being cut in line; if finality is weak, people will feel uncertain. Recently, a certain region has been discussing tax increases and regulatory looseness, and with deposit and withdrawal expectations changing, everyone becomes more sensitive. When the network is congested or transactions are slow to be packaged, emotions tend to flare up... I keep it simple myself: don't max out your position, being able to sleep peacefully is better than anything.
