Yes,cryptocurrency can be used in money landering, terrorism and in any illegal activities since bitcoin was created. And that is the reason why other people dont want to learn about this technology, cause the first time they hear about this is all about scam,frauds and something like that.
That's the truth. I have a close relative who doesn't care to understand anything about bitcoin and believes everything she hears on the news about it, which I assume is mostly negative. And if she did question news reports, she might realize that most drug deals, terrorism funding, and every other illegal activity has been and continues to be funded primarily with fiat currency, not cryptocurrency. The media doesn't mention that, unfortunately. Bastards.
Bitcoin can survive bad press, tho. It has before and will again and it isn't exactly headed toward $0. In fact it's far from that right now, so obviously traders and people interested in crypto are not influence by the news or the trivial fact that bitcoin might be used for illegal stuff. It's a bunch of BS.
