Crypto Basics

Bitcoin is a decentralized digital currency that allows peer-to-peer transactions without banks or intermediaries. It was created in 2009 and is the foundation of the cryptocurrency market.

What is Bitcoin?

Bitcoin is the first cryptocurrency ever created. Unlike traditional money controlled by governments or banks, Bitcoin runs on a decentralized blockchain network that records every transaction securely.

Why is Bitcoin important?

Bitcoin is important because it introduced a new financial system that is open, transparent, and not controlled by a single authority. It also inspired thousands of other cryptocurrencies and blockchain projects.

How does blockchain work?

Blockchain is a digital ledger that stores transaction data in blocks linked together in chronological order. Once information is recorded, it is extremely difficult to change, making blockchain secure and trustworthy.

What are altcoins?

Altcoins are cryptocurrencies other than Bitcoin. Examples include Ethereum, Solana, and Cardano. Some altcoins focus on smart contracts, faster transactions, or specific blockchain applications.

What is a crypto wallet?

A crypto wallet is a tool that allows users to store, send, and receive cryptocurrencies. Wallets can be software-based (hot wallets) or physical devices (cold wallets) for extra security.

Hot wallets vs cold wallets

Hot wallets are connected to the internet and are convenient for daily use, but they are more vulnerable to hacking. Cold wallets are offline and provide stronger security for long-term storage.

What is a crypto exchange?

A crypto exchange is a platform where users can buy, sell, and trade cryptocurrencies. Popular exchanges include Binance, Coinbase, and Kraken. Exchanges make it easy for beginners to enter the crypto market.

Crypto safety tips

Never share your private keys or recovery phrase. Always use two-factor authentication, verify website URLs carefully, and avoid offers that seem too good to be true.
