What Is Cryptocurrency?
Cryptocurrency (Cryptocurrency) is a virtual, intangible currency that operates using blockchain technology.
Key features include decentralization, distributed ledger systems, and encryption. Blockchain relies heavily on cryptography—complex mathematical algorithms secure transactions and wallet addresses, preventing tampering while ensuring privacy.
The most well-known cryptocurrency is Bitcoin (BTC), launched in 2009. Since then, thousands of alternative cryptocurrencies (altcoins) have emerged.
Pro Tip: While all cryptocurrencies are virtual currencies, not all virtual currencies qualify as cryptocurrencies. Only those issued and secured via blockchain encryption are true cryptocurrencies.
