That anchor wants to gain popularity Big businessmans campaigns and rooting a lot on bitcoin. They are promoting it because it is one of the biggest cryptocurrency in the world. All over the world it has about a millions users and also has a thousands of scammers. Bitcoin will be only dangerous if you trust anyone that you don't really know them personally and your entrusting them your bitcoin the you're such a dumb. Bitcoin is in the Internet. Internet is dangerous, if you are not careful about holding and entrusting some with your bitcoin then you'll get scammed.
