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?
The issue of illegal use of Bitcoin is indeed a challenge that the cryptocurrency community faces, and it's essential to address it to ensure wider adoption and legitimacy of Bitcoin. One possible solution to this problem is using blockchain analytics tools that can help track illicit transactions and identify the individuals involved. The second possible solution could be developing decentralized exchanges with robust KYC (Know Your Customer) and AML (Anti-Money Laundering) procedures in place. But his should be taken seriously.
Once you use the KYC process, it is never called decentralized, and we don't need to come up with any solution in this case. Why are people always afraid about bitcoin being used by criminals will make bitcoin bad or not good? Don't forget that before bitcoin was born, criminals used fiat money, gold... all other assets for their crimes. Why don't we find a solution to those things but blame bitcoin? If you want that to stop, you don't need to find a solution for bitcoin, instead, tell the government to find a way to kill the criminals because it's their responsibility.
