Cryptocurrencies, led by Bitcoin, have captured global attention as a revolutionary financial asset. Despite their volatility—Bitcoin recently swung from a record high of $42,000 to $29,000 within weeks—their adoption grows exponentially. Businesses, from football clubs like Madrid’s DUX Internacional to multinationals like PayPal, now accept crypto payments. But what exactly are cryptocurrencies, and how can investors navigate this complex landscape?
What Is a Cryptocurrency?
A cryptocurrency is a digital currency secured by blockchain technology, a decentralized ledger verified by independent programmers. Unlike traditional money, cryptocurrencies operate without central banks, offering peer-to-peer transactions with reduced fees.
- Bitcoin: Launched in 2008 by the pseudonymous Satoshi Nakamoto, Bitcoin pioneered decentralized finance.
- Key Feature: Limited supply (21 million coins), making it inflation-resistant.
