The news of Trump holding Bitcoin (reportedly worth millions of dollars) has the following major impacts on the cryptocurrency sector:

1. **Boosting Market Sentiment:** The public holding by a political celebrity, especially a former president, is seen as a strong endorsement for cryptocurrency, which may enhance market confidence and attract new attention.

2. **Increased Political-Linked Trading:** It may stimulate trading activity of MEME coins (such as $TRUMP) related to Trump or the Republican Party, triggering short-term speculation.

3. **Reinforcing 'Crypto-Friendly' Label:** It solidifies Trump's and the Republican Party's image as part of the 'pro-cryptocurrency' camp, which may influence voter tendencies (especially among cryptocurrency users).

4. **Impact on Policy Expectations:** It raises market expectations for potentially more lenient cryptocurrency regulatory policies if he is elected.

**Summary:** Significantly positive for market sentiment in the short term, especially for related concept coins; long-term impact depends on actual policy implementation. However, attention should be paid to market volatility risks, as a single event is not a decisive factor.
