A different kind of money that works online is cryptocurrency. It does not need any authority or institution to control it. It works with a system known as blockchain, which is like a big book that keeps track of all the deals and anyone can see it. The blockchain is not managed by anyone because it is shared by many computers that check each other.
Cryptocurrency and regular money have different pros and cons. Cryptocurrency is quick, secure, and lucrative, but also risky and complex. Regular money is steady and easy to use but also has limitations. Your choice depends on what you want and how much you can risk. You should learn how both types of money work and compare them before you decide.
