Binance co-founder and former CEO Changpeng Zhao, better known as CZ, has made it clear—he’s never bought a meme coin or an NFT.

On Sunday, CZ expressed his commitment to “fundamentals” in crypto, distancing himself from the hype-driven meme coin culture that continues to dominate parts of the industry.

“I haven’t bought a single meme coin so far,” he tweeted Sunday, adding his holdings are limited to Bitcoin (BTC) and BNB (BNB).

“I am not into sports cars; I don’t collect art; I haven’t bought any NFTs; I also haven’t bought most altcoins,” CZ wrote. “But I am not against any of the above.”
