The trading activity of cryptocurrency derivatives, such as futures and options, affects investors' price expectations. If the trading volume of Bitcoin futures increases by 50 - 100%, it may lead to a 10 - 20% increase in short - term price expectations as investors anticipate price movements. In the long - term, if the open interest in Ethereum options increases steadily, it may make investors more confident in the long - term stability of Ethereum's price, leading to a more stable price trend with less short - term volatility. The leverage trading in the derivatives market can also amplify price movements. A 2 - 3 times leverage can cause price fluctuations in the underlying cryptocurrency to be magnified by 50 - 100%, either driving prices up or down more sharply depending on market sentiment and trading positions.
