This remark produces mixed feelings for me. On one end, I would like to agree. On the other end, I also disagree. What you have observed is mostly true. But you cannot call people cowards because of this type of behavior. When you have seen many people around you go broke from blind investment, you won't easily let go of your money either. The trick is never to invest what you are not ready to let go of. And most people just don't have plenty to let go of. However, the more money you earn from Bitcoin, the more you're willing to invest.
