After watching my parents lose a chunk of their retirement savings in the 2008 crash, I've been overly cautious with my own investments—mostly index funds and bonds. But lately, a friend who put 10% of his portfolio into crypto and tech stocks is bragging about triple-digit gains, and I'm second-guessing my conservative approach. Is playing it safe really the smarter long-term strategy, or am I just letting past trauma dictate my financial decisions?
