When it comes to spot trading, market data never lies. A major CEX pulled in a staggering $7 trillion in spot volume throughout 2025, capturing 41% of the market among leading exchanges. That's 4.6 times the volume of another top player and roughly 5 times what a mid-tier platform processed. The dominance here is real. What makes this even more interesting is how both Bitcoin and altcoins fueled this activity—neither asset class took a back seat. Whether traders were rotating between BTC and alts or hunting for the next opportunity, this exchange maintained its grip on the lion's share of altcoin trading action. The numbers tell a clear story: when serious volume happens in spot markets, the market leaders capture the bulk of it.
