Hot topic development usually follows a pattern: a positive news, policy trend, or ecological breakthrough triggers the theme, such as switching ecological tracks, a new proposal for a certain public chain, or breakthroughs in cross-chain technology. However, who will be the leader on the day of explosion is often still uncertain.

**Day 1: Arbitrage Opportunities in the Game Phase**

It's difficult to hit the limit up on the day of explosion, but arbitrage opportunities exist. Focus on contracts or spot assets with the fastest gains within the theme, and confirm that the increase truly reaches expectations (e.g., doubling). Note that this is purely a game phase—positions must be kept light. The reason is simple: you can't judge whether the theme can continue or if it will be a one-day wonder.

**Day 2: The Moment of Certainty**

The key is to observe the continuation of the theme. If more than five coins appear with limit-up surges during bidding, it indicates the theme's strength has been confirmed, and you can increase participation.

Operate according to different situations:
- For assets with around 10x gains, there are usually phenomena of straight limit-up and turnover. The second limit-up position is the best entry point for turnover—this is the core of "2-limit-up determines the leader."
- For strong assets exceeding 20x, buy the one that hits the fastest limit-up. For example, if coin A broke out yesterday but coin B is stronger today, follow B (buy the strong, not the weak). When the bidding confirms more than five limit-ups and the 20x asset has reached the second limit-up, the certainty is highest, and full positions can be considered.

**Day 3: Screening Phase**

Continue to favor the strong over the weak. Focus on 10x assets that have already formed a straight limit-up, and on 20x assets showing strong performance in bidding. At this stage, more dynamic adjustments are made based on real-time bidding data.

**Logical Summary**

The first limit-up is purely a game; the second limit-up is where certainty begins. The appearance of five limit-ups is a watershed for theme strength and a signal to shift from light speculation to main force accumulation. When reaching the 20x second limit-up stage, if the theme's continuation is confirmed, full positions have a high probability of success.
