What Is Cryptocurrency?
Cryptocurrencies are digital assets that run on blockchain technology. This guide explains what cryptocurrency is, major assets like Bitcoin and Ethereum, how to read a crypto heatmap, and the risks to keep in mind.
What is cryptocurrency?
A cryptocurrency is a digital asset that operates on a distributed ledger called a blockchain, without relying on a central authority such as a bank or government. Transactions are secured by cryptography and verified by participants in the network.
Unlike traditional money, cryptocurrencies are usually decentralized — they are not controlled by any single institution.
Bitcoin, Ethereum and altcoins
- Bitcoin (BTC): The first and largest cryptocurrency, often seen as 'digital gold' or a store of value.
- Ethereum (ETH): A platform for smart contracts and decentralized applications (DeFi, NFTs).
- Altcoin: Any cryptocurrency other than Bitcoin (Solana, XRP, Cardano, etc.).
- Stablecoin: Low-volatility crypto pegged to a fiat currency, usually the US dollar (USDT, USDC).
Market cap, volume and volatility
A cryptocurrency's market cap = circulating supply × price. Volume shows how much was traded over a period and indicates liquidity.
Cryptocurrencies are highly volatile; prices can rise and fall sharply in a short time. That means both opportunity and risk.
How to read a crypto heatmap
When you switch to the Crypto market in Heaticker, you see the top 100 coins grouped by category (Layer 1, DeFi, Meme, etc.) on a heatmap. Green means up, red means down, and tile size reflects market cap.
Crypto data is real-time (there's no ~15-minute delay like stocks), so you can follow the market live. Stablecoins are hidden from the main view so you focus on real price moves.
Risks to keep in mind
- High volatility: Sudden, large price swings.
- Regulatory uncertainty: Legal status varies by country.
- Security: Wallet/exchange security and scam risks.
- Do your research: Understand the project, team and use case before investing.
