Not investing in Bitcoin was not a mistake.
An action is a mistake where sufficient due diligence/research could have given you proper information and you could have made a more informed decision. But you either choose to be lazy or trust the wrong person, that is a mistake.
Any amount of due diligence or research could not have told you the future of crypto. Since there was no way you could have gotten this information at that point, your actions were not a mistake with the perspective of the information you possessed or could have possessed. It looks like a mistake only with the gift of hindsight.
If you start evaluating your past actions with the information you have today, you'll find you've made a lot of mistakes but you won't have any resources to correct those mistakes. So you should evaluate your actions only with respect to the information you did or could have possessed at the time the action was taken.
