Example: Paying for coffee with Bitcoin via the Lightning Network.

Limit Order — An order to buy or sell an asset at a specific price (or better). Unlike market orders, they do not execute immediately if the target price isn’t met.
Example: A limit buy order for ETH at $1,800 will only execute if ETH falls to $1,800 or lower.

Liquid Staking — A process where users stake tokens and receive a tradable token (LST) representing the staked amount, allowing them to keep earning staking rewards while using the token elsewhere.
Example: Staking ETH with Lido gives you stETH, which can be used in DeFi while your ETH remains staked.

Liquidation — The forced closure of a leveraged position when the collateral is insufficient to cover losses.
Example: A 10x leveraged long on BTC may be liquidated if BTC falls 10% against the position.
