Some people don't see Bitcoin as a normal currency and think it's too risky because its value can change a lot. They also worry that it's used by criminals for illegal activities like money laundering. However, other people think Bitcoin is amazing because it's different from traditional currencies and could change how we use money. Nobody knows for sure what will happen to Bitcoin in the future, but people are still talking about it and interested in it.
Those people that worry about bitcoin being used for criminal or illegal activities don't really understand bitcoin, and one of my questions to such people will always be..
In what year was bitcoin born? - 2009
Before 2009, weren't there criminal and illegal activities carried out in majorly every part of the world?
Believing that bitcoin is used to finance criminal and illegal activities is the wrong mindset about bitcoin, without bitcoin many year back, crime has been, and if for instance, there is no bitcoin at the moment, crimes will still happen, this is something people should understand and stop worrying over things that are not important.
