Frequently Asked Questions

Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates on a technology called blockchain. Unlike traditional currencies, cryptocurrencies are decentralized and not controlled by any government or financial institution. Bitcoin, created in 2009, was the first cryptocurrency. Learn more in our complete beginner's guide.

Blockchain is a distributed ledger technology where transactions are recorded in "blocks" that are linked together in a chain. Each block contains a cryptographic hash of the previous block, making it virtually impossible to alter past transactions. This creates a transparent, secure, and immutable record of all transactions. For a detailed explanation, read our Blockchain Explained guide.

Bitcoin (BTC) is the world's first cryptocurrency, created by the pseudonymous Satoshi Nakamoto in 2009. It is a decentralized digital currency that allows peer-to-peer transactions without the need for intermediaries like banks. Bitcoin is often called "digital gold" and is the largest cryptocurrency by market capitalization. Learn about Bitcoin as an inflation hedge and Bitcoin ETFs.

Ethereum (ETH) is more than just a cryptocurrency — it's a decentralized computing platform that enables smart contracts and decentralized applications (dApps). While Bitcoin focuses primarily on being a digital currency, Ethereum provides a platform for building blockchain-based applications. Smart contracts on Ethereum power DeFi, NFTs, and countless other innovations. Explore Ethereum Layer 2 scaling solutions.

You can buy cryptocurrency through centralized exchanges (like Coinbase, Binance, or Kraken) or decentralized exchanges (DEXs). You'll typically need to create an account, verify your identity, deposit funds, and then place an order. After purchasing, it's recommended to transfer your crypto to a personal wallet for security. Read our crypto wallets guide to learn about storage options.

A cryptocurrency wallet stores your private keys and allows you to send, receive, and manage your digital assets. Wallets come in two main types: hot wallets (connected to the internet, convenient for everyday use) and cold wallets (offline storage, more secure for long-term holding). For a detailed comparison, see our complete crypto wallets guide.

DeFi, or Decentralized Finance, refers to financial services built on blockchain technology that operate without traditional intermediaries like banks. DeFi platforms offer lending, borrowing, trading, and earning yield through smart contracts. These services are open to anyone with an internet connection. Learn about DeFi lending and borrowing and staking and yield farming.

Staking involves locking up your cryptocurrency to support network operations (like validating transactions) in exchange for rewards. It's available on Proof-of-Stake (PoS) blockchains like Ethereum (after The Merge). Staking is a way to earn passive income on your crypto holdings. Use our staking rewards calculator to estimate potential earnings.

Cryptocurrency prices are primarily determined by supply and demand dynamics on exchanges. Factors that influence prices include market sentiment, adoption rates, regulatory news, technological developments, macroeconomic conditions, and overall market trends. Learn how to analyze markets in our market analysis strategies guide and crypto charts guide.

Impermanent loss occurs when you provide liquidity to an automated market maker (AMM) pool, and the price ratio of the paired assets changes compared to when you deposited them. The loss is "impermanent" because it can reverse if prices return to their original ratio. Use our impermanent loss calculator to estimate potential losses before providing liquidity.

Essential security practices include: using hardware wallets for long-term storage, enabling two-factor authentication (2FA), never sharing your private keys or seed phrases, using unique passwords, avoiding suspicious links and downloads, and keeping your software updated. For a complete overview, read our crypto security tips guide.

Common crypto scams include phishing attacks, Ponzi schemes, fake exchanges/wallets, rug pulls in DeFi, social media impersonation, and "pump and dump" schemes. Always verify URLs, never respond to unsolicited investment offers, and be skeptical of promises of guaranteed returns. If it sounds too good to be true, it probably is.
