In general, it's not advisable to trust projects solely based on their blockchain affiliation, and this isn't exclusive to the BNB chain. I've observed numerous scam projects across various chains, indicating that scammers continuously migrate to different chains to target newcomers. Therefore, it's crucial to utilize project/token scanners, conduct extensive research, and ask numerous questions before investing. Avoid succumbing to FOMO simply because a project is being promoted by others.
Ultimately, it's your money, and you bear the responsibility for its outcomes.
