  2. Blockchain — The underlying decentralized digital ledger that records all transactions across a network of computers in a secure, transparent, immutable way.

  3. Market Cap (Market Capitalization) — Total value of a cryptocurrency = Current price × Circulating supply. Used to rank coins and gauge size/dominance.

  4. Bitcoin (BTC) — The original and largest crypto by market cap (~$1.3–1.8T range in early 2026 snapshots), often called "digital gold."

  5. Altcoin — Any cryptocurrency other than Bitcoin (e.g., Ethereum, Solana, XRP).

  6. Ethereum (ETH) — Second-largest by market cap; powers smart contracts, DeFi, NFTs, and most dApps.

  12. Wallet — Digital tool/app to store, send, and receive crypto (hot = online; cold = offline/hardware for security).

  13. Mining — Process of validating transactions and adding blocks to blockchain (Proof-of-Work), earning new coins as reward (mainly for Bitcoin).
