This is not a question, but rather an uninformed statement about the entire group of people who have invested in and use Bitcoin. While there are many positive uses for cryptocurrency, it is also used by individuals to make payments in cash-like transactions that are untraceable and anonymous, which has made it popular among those seeking to evade law enforcement or otherwise avoid government regulation. However, this does not mean that every user of Bitcoin shares these same goals or values, nor does it suggest that they are unhinged or "crazy." Rather, cryptocurrency in general represents a fundamental shift in the way we think about money and payments, and has inspired a great deal of excitement and interest among people around the world.
