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 of cryptocurrency, which may enhance market confidence and attract new attention.

2. **Increase in Politically Associated Transactions:** This may stimulate the trading activity of MEME coins related to Trump or the Republican Party (such as $TRUMP), triggering short-term speculation.

3. **Strengthening the 'Crypto-Friendly' Label:** This solidifies Trump's and the Republican Party's image as part of the 'pro-cryptocurrency' camp, potentially influencing voter tendencies (especially those in the crypto community).

4. **Impact on Policy Expectations:** This raises market expectations for the implementation of more lenient cryptocurrency regulatory policies if he is elected.

**Summary:** Short-term significantly positive for market sentiment, especially for related concept coins; long-term effects will depend on the actual policy implementation. However, it is important to note the risk of market volatility, as a single event is not a decisive factor.
