#交易流动性 trading liquidity refers to the ability to quickly buy and sell assets at reasonable prices in the market. On trading platforms like Binance, a trading pair with high liquidity means there are a large number of buy and sell orders, allowing traders to easily find counterparties for transactions, with smaller bid-ask spreads and lower transaction costs. Assets can also be converted more quickly into cash or other assets. If one selects less popular currencies, there may be larger bid-ask spreads and greater slippage, which increases transaction costs and can easily lead to losses; this is what is meant by poor trading liquidity.
