Example: Bitcoin, Ethereum, and Litecoin are all cryptocurrencies.

Examples: Coinbase (centralized) and Uniswap (decentralized).
10. HODL
Definition: A slang term that originated from a misspelling of “hold.” It refers to the strategy of holding onto your cryptocurrency investments for the long term, despite market fluctuations.
Context: Often used in the crypto community to encourage patience during market dips.
11. FOMO (Fear of Missing Out)
