1.1 Example | high liquidity
Assets with high liquidity can be bought and sold en masse while not effecting the market price. These assets have a lot of depth on their order books, which allow for purchases of thousands, or even millions of dollars worth of an asset without shifting the price.
1.2 Example | low liquidity
Assets with low liquidity are very hard to buy or sell in large amounts. They usually have sparse order books, so trying to sell or buy any non-trivial amounts will cause significant changes to market price and market cap.
