Bitcoin is the first digital currency created in 2009 by a mysterious figure named Satoshi Nakamoto. Bitcoin operates without banks or third parties, using blockchain technology to record all transactions transparently and securely. Many people see Bitcoin as a long-term investment asset because its total supply is limited to only 21 million coins. Its value can fluctuate rapidly, making it a high-risk asset. Nevertheless, Bitcoin remains popular due to its decentralization and potential as a replacement for traditional financial systems. Currently, Bitcoin is used for transactions, investment, and as a store of value in various countries around the world.
