What is Bitcoin?

Bitcoin is the world's first decentralized digital currency, created in 2009 by an anonymous person or group known as Satoshi Nakamoto. It runs on blockchain technology — a public, transparent ledger that records every transaction. No bank, government, or central authority controls it. There are only 21 million Bitcoin that will ever exist, making it scarce by design.

What is Ethereum?

Ethereum is more than just a cryptocurrency — it is a programmable blockchain platform. Developers use it to build decentralized applications (dApps) and smart contracts that execute automatically without intermediaries. ETH is the native token used to pay for transactions and computations on the network.

What is a Crypto Wallet?

A crypto wallet is a digital tool that stores your private keys — the passwords that give you access to your cryptocurrency. Hot wallets (software, apps) are convenient for daily use. Cold wallets (hardware devices) are safer for storing large amounts long-term. You don't actually store coins — you store the keys that prove ownership.

What is Market Cap in Crypto?

Market capitalization = current price × total circulating supply. A coin priced at $1 with 1 billion coins in circulation has a $1 billion market cap. Higher market cap generally means a more established, less volatile asset. Bitcoin and Ethereum dominate with the largest market caps in the industry.

What is DeFi (Decentralized Finance)?

DeFi refers to financial services — lending, borrowing, trading, earning interest — that operate without banks or brokers, running entirely on smart contracts. Platforms like Uniswap, Aave, and Compound allow anyone with a crypto wallet to access financial services globally, 24/7, without approval from any institution.

Is Cryptocurrency a Good Investment?

Crypto offers high potential returns but comes with high risk. Prices can rise or fall 50% or more within weeks. Key principles: never invest more than you can afford to lose, diversify across multiple assets, and think long-term. Bitcoin and Ethereum have historically recovered from major crashes and reached new highs over multi-year cycles.

Crypto vs Stocks — Which is Better?

Both have their place. Stocks are regulated, may pay dividends, and tend to be less volatile. Crypto markets are open 24/7, unregulated in most countries, highly volatile, and offer no dividends. Many investors hold both — stocks for stability, crypto for growth potential. Your choice depends on your risk tolerance and investment horizon.

How Are Crypto Prices Determined?

Crypto prices are driven by supply and demand on exchanges worldwide. Key factors include: breaking news and regulations, large investor (whale) movements, macroeconomic events like interest rate changes, technological upgrades, and overall market sentiment. Unlike stocks, there are no earnings reports — price is purely what buyers and sellers agree on at any given moment.
