1. What is cryptocurrency?
Cryptocurrency is a digital or virtual currency that uses blockchain technology for secure, transparent, and decentralized transactions. It eliminates intermediaries like banks, allowing peer-to-peer payments worldwide. Bitcoin was the first, and thousands now exist, including Ethereum, BNB, and Solana.

2. How does blockchain work?
Blockchain is a distributed ledger that records transactions in blocks linked chronologically. Once a block is verified, it cannot be changed, ensuring security and transparency. Each participant (node) keeps a copy, making manipulation nearly impossible.

3. What makes crypto valuable?
The value of a cryptocurrency depends on its utility, scarcity, community adoption, and network demand. Like traditional assets, market perception and investor confidence also play major roles in price movements.

4. What is a crypto wallet?
A crypto wallet stores private and public keys that let you send, receive, and manage cryptocurrencies. It can be a hardware device (cold wallet) or an online app (hot wallet). Wallets protect your coins from unauthorized access.

5. What is a blockchain explorer?
A blockchain explorer is an online tool that lets you view live data on any blockchain—transactions, wallet addresses, gas fees, or block confirmations. Examples include Etherscan for Ethereum and BscScan for BNB Chain.

6. How do crypto transactions work?
When you send crypto, your wallet broadcasts the transaction to a network of nodes for verification. Once confirmed and added to a block, the transfer becomes permanent and visible on the blockchain.

7. What are altcoins?
Altcoins are cryptocurrencies other than Bitcoin. They include Ethereum, Ripple, Solana, and thousands more, each with different use cases such as smart contracts, privacy, gaming, or DeFi.

8. What is a stablecoin?
Stablecoins are cryptocurrencies pegged to stable assets like the U.S. dollar to reduce volatility. Examples include USDT, USDC, and BUSD. They are widely used in trading and cross-border payments.

9. Why is Bitcoin called digital gold?
Bitcoin is often compared to gold because it’s scarce (limited to 21 million coins) and serves as a store of value. Investors view it as a hedge against inflation and currency devaluation.

10. Can crypto replace traditional money?
Not entirely yet. While crypto offers speed and decentralization, most governments still rely on fiat systems. Over time, hybrid models like CBDCs (Central Bank Digital Currencies) may coexist with cryptocurrencies.

11. What is crypto trading?
Crypto trading involves buying and selling digital assets to profit from price changes. Traders analyze charts, news, and on-chain data to make informed decisions.

12. What’s the difference between spot and futures trading?
Spot trading means buying actual crypto to hold or sell later. Futures trading involves contracts that speculate on future prices—offering leverage but higher risk.

13. How do I start trading crypto?
Start by choosing a reputable exchange, verifying your account, funding it, and studying basic strategies. Always use secure wallets and avoid emotional trading.

14. What is technical analysis in crypto?
Technical analysis uses charts, indicators, and price patterns to forecast future movements. Common tools include RSI, MACD, and moving averages.

15. What is fundamental analysis in crypto?
Fundamental analysis studies the project’s purpose, team, tokenomics, and partnerships to determine long-term value beyond short-term price trends.

16. What are crypto trading pairs?
A trading pair shows two currencies you can exchange, such as BTC/USDT or ETH/BTC. It helps compare the value of one coin relative to another.

17. How much should I invest in crypto?
Only invest what you can afford to lose. Diversify your portfolio, and never borrow money for speculative trades. Start small and learn progressively.

18. What causes crypto price volatility?
Prices fluctuate due to market sentiment, news events, regulations, liquidity, and whale activity. Unlike stocks, crypto markets run 24/7, increasing volatility.

19. How can I protect my crypto investments?
Use strong passwords, enable 2FA, store long-term holdings in cold wallets, and avoid suspicious links. Stick to exchanges with proven security records.

20. Are crypto trading bots safe?
Only reputable platforms provide reliable bots. They automate strategies but still carry risk during high volatility. Always backtest and monitor them.

21. What is DeFi?
Decentralized Finance (DeFi) offers financial services like lending, borrowing, and staking without banks—powered by smart contracts on blockchains such as Ethereum.

22. What are smart contracts?
Smart contracts are self-executing programs that automatically enforce terms when conditions are met. They power DeFi, NFTs, and decentralized applications.

23. What are NFTs?
Non-Fungible Tokens (NFTs) represent unique digital assets—artwork, music, collectibles, or virtual real estate—secured by blockchain ownership proof.

24. What is Web3?
Web3 represents the next phase of the internet where users own data and digital identity, interacting through decentralized apps (dApps) rather than centralized platforms.

25. How do NFT marketplaces work?
NFT marketplaces like OpenSea and Rarible allow users to mint, buy, or sell digital assets using cryptocurrencies. Each transaction is recorded on-chain.

26. What are liquidity pools in DeFi?
Liquidity pools are collections of tokens locked in smart contracts to facilitate decentralized trading. Users earn rewards for providing liquidity.

27. What is yield farming?
Yield farming is the practice of staking or lending crypto assets in DeFi platforms to earn returns, often paid in governance or native tokens.

28. What are governance tokens?
Governance tokens let holders vote on project decisions like upgrades or protocol fees. They give users a voice in decentralized platforms.

29. Can NFTs lose value?
Yes. NFT value depends on demand, utility, creator reputation, and market trends. Many NFTs are speculative and can decline significantly in price.

30. How can I get started with Web3 apps?
Install a Web3 wallet like MetaMask, connect it to a blockchain network, and explore dApps for gaming, finance, or collectibles.
