In a big bull market, many people not only didn't make money but also lost a lot. Reasons:

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

2. Played in the primary market, bought Pi Xiu coins and couldn't sell them.

3. Only traded contracts with high leverage and unfortunately got liquidated.

4. Lacked security awareness, got scammed, phishing.

5. Wallet was stolen, withdrawals frozen.

6. In a bull market, didn't understand cashing out, still wanted to earn more.
