Some people use Bitcoin in illegal transactions as they know that they are not traceable but never think that they could be successful all the time. I understand why some countries are not in the support of crypto because of this, but even illegalities hidden the authorities will still hunt them down.

Yeah, and the same with you...I wont seeing that the world needs for Bitcoin because of its high risk and volatility feature. Not even we consider that it places an important role at this time as we use it for another form of cashless payment it is because traditional payment won't either stop. And we know that, people are not 100% committed to crypto adoption and being much comfortable with this.
