#交易流动性 Trading liquidity refers to the ability of an asset to be bought and sold quickly at a reasonable price. In the cryptocurrency market, trading pairs with high liquidity, such as Bitcoin, Ethereum, and other mainstream cryptocurrencies, have a large number of buyers and sellers, making transactions easy to execute with a small bid-ask spread. In contrast, trading pairs with low liquidity may have fewer buyers and sellers, leading to inactive trading and larger bid-ask spreads, which can expose investors to significant price volatility risks and transaction costs when buying and selling.
