Unlike traditional currencies issued by governments (fiat currencies), Bitcoin is not controlled by any central authority or government. Instead, it relies on a technology called blockchain to secure transactions and control the creation of new units.
Bitcoins can be bought, sold, or exchanged for other currencies on various online platforms and can also be used for transactions with merchants who accept them as payment. The value of Bitcoin can fluctuate significantly, and its price is determined by supply and demand in the market.
People often see Bitcoin as an investment opportunity due to its potential for high returns but also acknowledge its volatility and the risks associated with investing in it.
