This company in South Korea is figuring out that once a cyber criminal, always a cyber criminal. They found that two separate big crypto crimes shared the same exchange account for onramping or offramping. Of course most of it was done with Bitcoin. Don't know how it will get better before getting worse.
https://thenews.asia/hyungoo-kim-tracking-cryptocurrency-cyber-crimes/I always wonder why people are so greedy. Well, you have committed a crime, for example, earned a few million dollars on it that will last you for the rest of your days, and also your children, too. Why are you going to do this again putting yourself in danger of losing everything and going to prison where you will eat unleavened porridge? Unclear.
The answer for the question is so simple people want to earn huge money, they don't think about getting in prison or even they can destroy lives since the most important for those scammers is they can benefit on their actions eventhough they stepped on the innocent persons. Many scammers knew that they are hard to trace especially in online so best for people to be careful since scammers don't have any conscience.
