Definition
Liquidity is the ease with which an asset can be bought or sold without significantly moving its price. A highly liquid market has many buyers and sellers and tight bid-ask spreads, so even sizeable orders fill near the quoted price. A thin (illiquid) market has few participants and wide spreads, so a single large order can swing the price sharply. Liquidity is about execution, not value: an asset can have a large notional size yet be hard to actually trade.
Why it matters more than headline numbers
A high market capitalization does not guarantee liquidity — market cap is price times supply, but most of that supply may never be on the market. The real question for anyone moving size is how much can be bought or sold before the price moves, which depends on order-book depth across exchanges. This is why thinly traded assets can show impressive market caps that evaporate under any real selling pressure.
Relevance to Bitcoin and miners
Bitcoin is among the most liquid crypto assets, trading deeply across many venues, which is part of why it is used as the market's reserve asset and base trading pair. For miners, liquidity matters when selling produced coins to cover costs: a liquid market lets a treasury sell steadily with minimal slippage, while illiquid conditions force worse fills. Large holders, or whales, can strain liquidity when they transact.
