So I want to hear your opinion: how to make bitcoin technology "safer" so we could fight a crime committed with crypto and help with bitcoin adoption without taking away the main features of bitcoin like decentralization and anonymity?
Bitcoin is also just a currency like a fiat and they are used by people. So we won't have any way to restrict the usage from criminals, if there is any way, the government will do it with fiat, not just bitcoin, because fiat is used by criminals hundreds of times more than bitcoin. The government does not accept bitcoin because its decentralization threatens their power, it has nothing to do with criminals using bitcoin.
