Many people don't really care about whether Bitcoin is a scam. They just want to get a sense of "I'm right" after expressing their opinions on something. They are poor people, a bunch of poor people who talk endlessly but take care of him as soon as they get the money. Sometimes I feel that I have seen a lot in the currency circle, but I am often ashamed, because occasionally I am also one of those poor people. So I always remind myself that I can be constrained by my own insights, but I cannot stop reflecting and learning. Maybe I know a lot about the currency circle, but I'm sure I know very little.
