A call option is a contract that gives you the right to buy an underlying crypto asset at a specific price. Call options increase in value as the underlying asset increases in value. Calls go up when the prices go up. It is the opposite of a put contract.
Buying call options let you jump on a moonshot, worry-free: they offer all the upside potential of a token's rise without the downside risk if it crashes.
They offer leverage: call options can deliver higher percentage returns. Think a token is making a jump? Use call options to get more upside than buying tokens outright.
They can remove impermanent loss: buyings call options on a project lets you provide liquidity AND catch the upside if a coin moons — all without having to buy more tokens.
Selling call options lets you get paid for selling the top: if you are looking for a way to earn extra money on your bag, selling a call is the way to go. Set a sell price you're comfortable selling at and get paid a premium by someone for the right to buy your tokens at that price in the future.
