Anyway, if you do not have good arguments, usually someone who opposes the idea of bitcoin says, that the criminals use bitcoin.
Privacy is not only a right, it is a must we need to practice but sadly, many turn blind to their lifestyle being exposed to the public, They would rather be happy taking pictures and using Facebook apps and TikTok to show the progressive stage of their life but their information are been collected in underground. When I see a celebrity that has no social media account, it gives me adrenaline but most people don't know that private life is a happy life, not everything we must show the public but people don't just care about privacy a bit.
Before bitcoin was born crimes were around every corner and till today that bitcoin has matured to this stage, the crime rate is high, the fiat of the government system is not far from this but they will rather turn a blind eye to these things and focus on bitcoin and that's jealousy, they don't have power over it and it give them headache how people spend without knowing more about the spending history.
