The crypto world is a vast and constantly evolving realm of cryptocurrencies, blockchains, and related technologies. It has several key aspects:
1. Cryptocurrencies are digital money based on blockchain technology. The most famous one is Bitcoin (BTC), but there are thousands of alternative coins (altcoins) — Ethereum (ETH), Binance Coin (BNB), Solana (SOL), and many others.
2. Blockchain is a distributed ledger that ensures the security, transparency, and decentralization of data. It forms the basis of all cryptocurrencies.
3. DeFi (decentralized finance) — financial services that operate without intermediaries (banks, brokers), based on smart contracts. Examples: lending, staking, cryptocurrency exchange.
4. NFTs (non-fungible tokens) are unique digital assets often related to art, music, and games.
5. Mining and staking are methods of extracting or earning income from cryptocurrency.
6. Cryptocurrency exchanges are platforms for buying, selling, and exchanging cryptocurrencies (Binance, Coinbase, Kraken).
7. Regulation and security are important topics due to the risks of fraud, hacking, and state regulation.
