No matter how cautious you are in the financial field, mistakes are inevitable—this is normal. The key is to learn how to filter. Truly worthwhile accounts have a few characteristics: solid professional background, rational and restrained discussions (don't chase sensationalism or hype all day), clear separation between investment advice and personal ideology, and respect for investors' memory and cognitive abilities. Such voices are already extremely scarce in the era of information bombardment. Spending more time finding these accounts is much more cost-effective than blindly following the trend.
