He's right, it's actually a bad idea to buy a coin that's listed on cex day 1

CZ, the founder of Binance, has expressed concerns about the current token listing process on the exchange. He highlighted that the method of announcing a listing followed by a four-hour delay before the token goes live can lead to market inefficiencies. During this period, token prices often surge on DEXs as traders rush to buy, and then sell once the token is listed on the CEX, potentially leading to unfair price manipulation.
