The trading volume of DEX/CEX has reached 20%, a record high. You should know that there are few quantitative funds in the world of DEX, and the volume-washing and counter-trading are not of the same order of magnitude as CEX.
So if we subtract the big guys in the front row such as Bitcoin, Ethereum, and Ripple, the trading volume of altcoins alone should be far ahead of CEX.
To put it bluntly, the liquidity of altcoins in centralized exchanges is being drained by DEX, which is why the altcoins you see are collapsing across the board.
What's more serious is that this trend has not slowed down. In other words, in the future, it is best to only use CEX to trade mainstream coins. Those small coins are unlikely to have much money-making effect.
