It’s Digital

Crypto exists entirely online. You hold it in a secure digital wallet and can send it to anyone, anywhere in the world, in minutes — 24/7, without a bank.

It’s Currency

Like cash or a card, crypto works as money. Instead of paper bills it’s counted in digital units called tokens that divide into tiny fractions, so you can buy $1 worth of Bitcoin rather than a whole coin. Ready to try it? See how to buy crypto.

It’s Decentralized

No single government, company, or bank is in control. Crypto runs on a global network of computers, which makes it censorship-resistant and open to anyone with an internet connection.

It Can’t Be Counterfeited

Cryptography makes tokens impossible to copy or forge. Every transaction is permanently recorded on a public ledger that anyone can verify.

It’s Built on Blockchain

Most cryptocurrencies run on a blockchain — a shared, tamper-proof ledger maintained by thousands of computers (nodes) around the world. That is what keeps the network secure and trustworthy without a middleman.

There Are Thousands of Cryptos

Since Bitcoin (BTC) launched in 2009, thousands of cryptocurrencies have appeared, each with different features and uses. The most established are Bitcoin (BTC) and Ethereum (ETH) — the usual starting points for beginners.

Key Properties at a Glance

• Digital & global
• Decentralized — no bank or government in control
