Just don't try to find hidden meaning and secret wisdom in CZ's posts. There's no hidden meaning. He just admits that day trading isn't for everyone and most day traders lose money in the long run. He is right about HODLing being better than trading, but I don't like the fact, that he is shilling his BNB altcoin.

By the way, I like the fact that CZ is being honest. He's the former CEO of Binance and centralized crypto exchanges like Binance want more day traders, so that the CEX could make more money. It would make more sense for a guy like CZ to make social media posts urging more people to sign up to Binance and start trading, but he is being honest about the potential risks of losing your money via day trading.
CZ is no longer a Binance CEO but he has his management impacts on Binance behind the scene and people consider CZ like God with anything he said, tweeted is right. I don't think so but I agree that CZ is very mindful and his experience in this market is enough for him to give valuable advice to many newbies in this market. His personal success from selling his apartment and fully invested his money in bitcoin, to his business success with Binance, are like motivating stories for anyone who want to join this market or are still as newbies in this market.
In recent months, Binance got a lot of drama since the CEO position changed to Richard Teng, Binance Alpha with many low quality projects, and the technical bugs from Binance that triggered 10 October market crash. CZ if is still a Binance CEO would be in hub of community criteques but fortunately he is no longer Binance CEO.
