Cryptocurrency trading volumes experienced a significant decline in December, with centralized exchanges (CEXs) seeing a 32% drop to $1.13 trillion, marking a 15-month low. This decrease follows a $1.66 trillion volume in November and $2.23 trillion in October. Binance led the CEX market with $367.35 billion in trading volume, followed by ByBit, HTX, Gate, and Coinbase. Analysts cite seasonal sentiment, reduced volatility, and year-end position adjustments as contributing factors. Decentralized exchanges (DEXs) also faced a downturn, with trading volumes falling to $245 billion, a 20% decrease from November's $306 billion and a 46% drop from October's $451.2 billion. Uniswap remained the dominant DEX, recording a trading volume of $60 billion for the month.
