How crypto earn works?

Cryptocurrencies work by issuing a finite number of tokens that can be used to conduct transactions. For example, Bitcoin has a cap of 21 million tokens. These tokens are then 'mined' by computers that complete complex mathematical calculations. The first computer to solve the equation is rewarded with a new token. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. This makes them attractive to investors who want more control over their money, and also allows for faster and cheaper transactions across borders. Cryptocurrencies are also less volatile than traditional currencies, making them a safer investment option.
