#USElectronicsTariffs uselectronics*Bitcoin (BTC)* is a digital currency created in 2009 by an anonymous person or group known as *Satoshi Nakamoto*. It is a *decentralized cryptocurrency*, which means it is not controlled by any government or bank. Bitcoin is based on blockchain technology, where every transaction record is kept securely. People use it to buy goods online, invest, and send money. Its supply is limited – only 21 million BTC will ever be created, which increases both its demand and price.
