Call Options

A call option is a financial contract that gives the holder the right, but not the obligation, to buy an underlying asset at a specified price by a certain date. Investors buy call options to profit from an expected increase in the price of the asset.

If the price rises above the strike price, the call option gains value, allowing the holder to purchase the asset at a discount. Calls are a primary tool for bullish speculation, providing leverage without the need to own the underlying asset directly.

In crypto, they are often used to capture massive upside moves during bull markets. The seller of the call option takes on the risk of having to sell the asset at a price lower than its market value if the price rises significantly.

It is a fundamental instrument for expressing bullish sentiment or hedging short positions.
