TikTok's financial advice has become popular, with trends like "cash stuffing" and "100 envelope" methods emerging. While these trends may provide temporary benefits, experts emphasize the importance of establishing a routine for lasting financial success. They recommend setting a budget, automating savings, and considering high-yield savings accounts, as relying solely on TikTok advice may be risky. It's crucial to vet financial advice, as not all information on social media is reliable.
