[Counterfeit Coins: Comparative Analysis of Two Mature Trading Playbooks] 1. The full life cycle chain of counterfeit coins: suppression and accumulation (strategy two) → accumulation completed and start of the pump → pump-up for distribution; high-altitude leap and plunge (strategy one) → go to zero. The two strategies can be used in sequence to run through the entire life cycle of a given coin. 2. Do not apply strategy one to a new coin that is still in the accumulation-and-suppression stage, and do not apply strategy two to an old counterfeit coin whose accumulation phase has already finished and which has started its pumping phase. If stages are mismatched, the strategy performance will be greatly reduced. 3. Both models adhere to the same underlying principle: do not predict price or time—only rely on objective signals from the order book, letting the dynamic watershed help us identify the main force’s actions.
