I was once scammed by a 'rug pull' in a DeFi new project. The project was initially packaged professionally, and the code was audited, but it quickly crashed and emptied the funds after launch. Since then, I understand that any project claiming 'high returns' and 'zero risk' is a trap. I now adhere to three anti-scam principles: 1) Do not engage with anonymous teams or projects without background; 2) Do not invest in anything that is not open-source or whose contracts cannot be verified; 3) Do not participate in private chats, group pulling, or red envelope inducements. The most important aspect of staying SAFU is self-discipline and a spirit of skepticism: the more eager you are to make money, the easier it is for scammers to succeed. Better to miss out than to be scammed.
