So there is different opinion among people about Bitcoin. Some people consider Bitcoin as "criminal money" because it's often used on the dark web and helps criminals to get away with selling drugs and stuff.
There are also people who think that Bitcoin is a bubble that will explode and lose its value, so they don't trust it. It's probably because these people don't know how Bitcoin and blockchain work.
And there is a third group of people who think that Bitcoin is used just for gambling so they don't want to buy it.
This is all because of the Government trying to control us and preventing us for getting the freedom which bitcoin offers. They spread all this negative rumors and news to create fear among us. And that's how this kind of mindset has been established. Criminals use money, gold, and any other currency to do their dirty deals. Has the government ever considered banning them? No!
So why only crypto? It's all about creating a controlling environment.
Like would it be good if we could create a system that somehow will make the life of criminals who use Bitcoin harder?
I don't think this will ever change anything. People will find out new ways of doing things. You can not completely prevent anything regarding Bitcoin as it is decentralized. So it is better not to think about those and focus on the positive side. As I said, it's all about creating fear. So it will better to avoid these.
