In a big bull market, why are many people not only not making money but also losing a lot?

1. All-in on shanzhai memes, ended up going to zero

2. Playing in the primary market, bought Pi Xiu coins that can't be sold

3. Only trading contracts, heavily leveraged, unfortunately got liquidated

4. Lack of security awareness, got scammed, phishing

5. Wallet was stolen, funds frozen
