Bitcoin is a decentralized digital currency introduced by Satoshi Nakamoto in 2009. Based on blockchain technology, Bitcoin enables peer-to-peer transactions without intermediaries like banks. This system uses cryptography to maintain the security and transparency of each transaction. The total number of Bitcoins is limited to twenty-one million coins, creating scarcity that influences its value. Many people see Bitcoin as both an investment asset and a hedge against inflation. However, price volatility and uneven regulation pose major challenges. In the future, Bitcoin has the potential to transform the global financial system and the way people store and transfer value digitally and across borders quickly, efficiently, securely, and transparently.
