Bitcoin

Bitcoin is a type of digital money that was created in 2009 by a person or group using the name Satoshi Nakamoto. Unlike regular money, like coins or dollar bills, Bitcoin exists only online. People can use it to buy things or send it to others through the internet without needing a bank. It works on a special technology called blockchain, which is like a big, secure notebook that keeps track of all Bitcoin transactions. Because there are a limited number of Bitcoins that can ever be created, many people see it as a valuable investment, similar to gold. However, its price can change a lot, making it risky for some.
