Here's how to use Binance Futures to hedge your cryptocurrency portfolio:

1. Understand the difference between one-way mode and hedge mode. One-way mode allows you to open a position in one direction only, while hedge mode allows you to open two opposite positions simultaneously.

2. Understand the hedge mode trading strategy. This strategy involves opening both long and short positions on the same contract at the same time to profit from market fluctuations while reducing potential losses.

3. Use hedge mode to mitigate risk exposure. Hedge mode allows you to balance your exposure to the futures market, so if one position suffers losses, gains in the opposite position help offset those losses.

4. Use hedge mode for position insurance. Hedge mode provides a safety net for traders during periods of market uncertainty, such as the onset of bearish trends or significant market news.

5. Use hedge mode for event-based trading. This strategy is useful around major crypto events and news, such as hard forks and regulatory announcements.

6. Use hedge mode when trading volatile altcoins. Compared to blue chip cryptocurrencies, most altcoins often exhibit more significant price fluctuations, so hedge mode can help you take advantage of such rapid price movements while protecting your capital.

7. Use hedge mode for detailed position analysis. In hedge mode, you can separately analyze the performance of your long and short positions for the same cryptocurrency pair, which helps you understand which aspects of your strategy are most effective and how different market conditions affect each side of your trade.

8. Use hedge mode for accurate performance tracking. When you reverse a trade in one-way mode, there's a risk of losing track of individual trade performance, as positions are aggregated. Hedge mode, on the other hand, maintains distinct records for long and short positions, allowing you to retain a clear view of your trading history, costs and the profitability of each trade.
