Crimes existed from the very beginning. People steals fiat money everyday. Did we ever say that "no criminal activities will take place with crypto currencies"? Nope, we never said that. Now people may argue that they are anonymously doing all those illegal activities using crypto currencies. Well, people used to do that same thing before crypto currencies were invented. They used prepaid cards or gift cards to do those illegal activities. It is just that the media starts to exaggerate when it comes to crypto currencies.
People who have known Crypto well will not care about the news about the crypto crime. Most beginners will believe what the news media says, so we don't need to worry that the news will make a big change because beginners will not have the power to influence crypto.
Stricter regulations against this kind of crime should be created and enforce to eliminate them and I believe that there are already a group of countries planning to enforce it globally. Cybercriminals have been trying to evade authorities by using the internet and high technologies for so many years now even before the cryptocurrencies exists. The regulation should also focus on identifying possible illegal transactions that made through the exchanges and track them.
It's useless, crime will be difficult to eradicate because evil will never end. Adding strict regulation will only eliminate the basic goal of crypto, which is decentralization. Someone goes to crypto to get freedom from all the annoying rules. Even KYC rules are still many people who object, what if the rules are added to more stringently.
