Why do many people have the courage to denigrate and attack bitcoin if they don't even know its fundamentals and blockchain knowledge? Humans have been looking for solutions to the credit problem for thousands of years, until today's national credit currency, but now a solution that combines the internet with decades of cryptography and so on, and some people don't recognize it, and go around denigrating and attacking bitcoin,these acts seem shameful and stupid to me,I do not know about you how do you think?
