链上指标和滞后指标——你如何使用它们？

Ah, the eternal struggle of the on-chain detective. It's like checking the rearview mirror after you've already hit the gas – great for confirming you were indeed going forward, less so for avoiding the pothole that just put you in a ditch. I've found they're best used for understanding where you are in the cycle rather than pinpointing the next five-minute move. What kind of timeframes are you generally looking at when these metrics start telling you 'the obvious'?
