It's a good philosophy, and one that is widely touted for any kind of investment, especially crypto. Unfortunately, in my humble opinion, it is a mantra that most of us do not entirely believe. I very much doubt that anyone invested in crypto either expects, or is willing, to lose every cent they've invested. I'm not saying that people are investing everything they own, but there's no question that a large number have (proportionally) invested far more than they would in any other similarly risky investment.
