Bitcoin is the world's first and most widely recognized cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto. It operates on a decentralized blockchain network, meaning no government or bank controls it. Bitcoin has a fixed supply cap of 21 million coins, making it a deflationary asset often compared to digital gold.
In November 2021, Bitcoin reached an all-time high of nearly $69,000 per coin. By early 2024, it surpassed $70,000 again — making early investors who held through the volatility extremely wealthy.
A blockchain is a distributed digital ledger that records transactions across a network of computers in a way that makes them virtually impossible to alter. Each "block" of data is cryptographically linked to the previous one, forming an unbreakable chain. Blockchain is the foundational technology behind all cryptocurrencies.
The Bitcoin blockchain has recorded every transaction since January 2009 without any successful hack of the core protocol. As of 2024, it processes over 300,000 transactions per day across the globe.
A crypto wallet is a software or hardware tool that stores the private and public keys needed to send and receive cryptocurrency. Unlike a physical wallet, it doesn't store the crypto itself — only the keys that prove ownership on the blockchain. Wallets can be hot (online) or cold (offline hardware devices).
Coinbase Wallet and MetaMask are two of the most popular software wallets in the US. The Ledger Nano is a popular cold hardware wallet that stores private keys offline, protecting against hackers.
Cryptocurrency mining is the process by which new transactions are verified and added to a blockchain and new coins are created. Miners use powerful computers to solve complex mathematical puzzles — the first to solve it gets to add the next block and earns a reward in cryptocurrency. Mining requires significant computing power and electricity.
In 2024, the US accounted for over 40% of global Bitcoin mining activity. Large mining farms in states like Texas and Kentucky use cheap energy to run thousands of specialized computers called ASICs.
An altcoin (alternative coin) is any cryptocurrency other than Bitcoin. Thousands of altcoins exist, each with different features, use cases, and levels of risk. Some altcoins, like Ethereum, have become major platforms in their own right, while others are highly speculative. The term covers everything from Ethereum and Solana to obscure meme coins.
Ethereum (ETH) is the largest altcoin by market cap, powering the majority of decentralized finance (DeFi) applications and NFT platforms. As of 2024, its market cap exceeds $400 billion.
A cryptocurrency exchange is a platform where users can buy, sell, and trade cryptocurrencies using traditional money or other digital assets. Centralized exchanges (CEX) are operated by companies and require account verification, while decentralized exchanges (DEX) operate via smart contracts without a central authority.
Coinbase is the largest US-regulated cryptocurrency exchange with over 100 million verified users. Binance is the largest exchange globally by trading volume, processing billions of dollars in transactions daily.
A crypto token is a digital asset built on top of an existing blockchain, rather than having its own native blockchain. Tokens can represent a wide range of things — from voting rights in a protocol to ownership of a digital asset (NFT) to a stake in a decentralized application. Most tokens are built on the Ethereum blockchain using the ERC-20 standard.
USD Coin (USDC) is a widely used ERC-20 token pegged 1:1 to the US dollar. It allows users to transact in stable digital dollars across DeFi platforms without exposure to crypto volatility.
A stablecoin is a type of cryptocurrency designed to maintain a stable value by being pegged to a reserve asset — typically the US dollar, euro, or gold. Stablecoins bridge the gap between volatile cryptocurrencies and traditional money, enabling fast digital payments without price swings. They are widely used in DeFi lending and cross-border payments.
Tether (USDT) is the world's largest stablecoin with over $100 billion in circulation. USDC, issued by Circle and Coinbase, is fully backed by cash and US Treasury bonds, making it one of the most transparent stablecoins available.
Bitcoin halving is an event that occurs approximately every four years (every 210,000 blocks) that cuts the reward for mining a Bitcoin block in half. This mechanism slows the creation of new Bitcoin, controlling inflation and maintaining scarcity. Halvings have historically preceded major bull markets, as the reduced supply of new coins meets consistent or growing demand.
The most recent Bitcoin halving occurred in April 2024, reducing the block reward from 6.25 BTC to 3.125 BTC per block. Previous halvings in 2012, 2016, and 2020 each preceded significant price increases within 12-18 months.
DeFi (Decentralized Finance) refers to financial services and applications built on blockchain networks that operate without traditional intermediaries like banks or brokerages. DeFi protocols enable lending, borrowing, trading, and earning interest using smart contracts — self-executing code that automatically enforces the terms of financial agreements.
Aave is one of the largest DeFi lending protocols, with over $10 billion in assets locked. Users can deposit crypto to earn interest or borrow against their holdings — all without filling out a loan application or speaking to a banker.
