If Bitcoin (BTC) continues to rise sharply, driving other altcoins to surge, I can introduce a trading strategy to lock in profits, namely the moving stop loss method. This method is divided into two steps:

1. **Set the initial take profit point**:

- Assuming that your expected target price is $100, and this price is also your psychological pressure point, you can set the take profit order at $100. This way, even if the price continues to rise, you can ensure that you lock in profits when the target price is reached.

2. **Adjust the take profit point according to price changes**:

- If your cost price is $30 and the current price has risen to $70, you can set the take profit stop loss order at $50. As the price rises further, for example, to $85, you move the take profit stop loss order up to $70. In this way, even if the market suddenly falls sharply, you can lock in most of the profits to a certain extent without having to watch the market all the time.

Ideally, the price can rise directly to your final target price of $100, and then you will execute the take profit operation, which is the most ideal result. But the cryptocurrency market is volatile and price fluctuations are often unpredictable, so we often need to be prepared for market changes.

Through this moving stop-profit method, you can reduce losses caused by sudden market reversals while maintaining profits. This is a risk management strategy that can help you enjoy the profits brought by market increases while also providing a certain degree of protection for your investment.
