The rollover strategy needs to pay attention to the following points:

1. **Sufficient Patience:** The potential profit of the rollover strategy is huge. Succeeding a few times is enough to make you earn tens of millions or even billions. Therefore, do not act lightly, and find opportunities with high certainty.
2. **Highly deterministic opportunities:** These opportunities usually refer to assets that have experienced a big dump and entered a sideways oscillation phase, and then break through upwards. In this case, the probability of continuing the strong trend is high. Seize the opportunity at the initial stage of trend reversal and enter in a timely manner.
3. **Only Rollover Longs:** In the rollover strategy, only long positions are usually considered, that is, trading is conducted when assets are expected to pump. The core of this strategy is to capture potential pump trends in order to gain profits.
In short, the rollover strategy requires careful timing and asset selection, and patience to wait for high-certainty trading opportunities to avoid blind operations. When choosing, pay special attention to the technical aspects and market sentiment of the assets, as well as the breakthrough signals at the reversal points, in order to effectively implement the rollover strategy and obtain the expected returns.
