It operates on blockchain technology, where transactions are recorded publicly and transparently. Bitcoin is not controlled by any intermediary organization, which helps to minimize risks related to inflation or government interference. The total supply of BTC is capped at 21 million, increasing its scarcity and long-term value. Bitcoin is used as a means of storing value, online transactions, and is the foundation of many current blockchain projects.
