It should have been obvious to anyone that people would do less day trading once they had anything better to do.
Or when making money became harder. Amazing the number of people I personally know who took 1 year of day trading to be the “norm” and made big life decisions based on their results. From quitting good jobs to buying houses they can’t afford, all because they made big money in 2021 and thought they could keep repeating it every year.
You should not take investment advice from people who have been doing it less than a decade. It takes time to sort out the lucky from the smart.
