So, if TV company advertise company that is a registered trademark but the product of that company says in TV commercial that one of it's side effect is death
You don't have to make it complicated. Advertising a product with deadly side effect would introduce other legal concerns. Let's just say that a TV commercial appeared whose company was later on caught to launder funds, and let's assume that company is anonymous for a while, so the feds can't just address the people in charge of the company. You think the TV commercial would continue?
So, I assume users were receiving bitcoins that were mixed and more likely some users would end up with bitcoins that were used for black market and other illegal activities.
Mixing Bitcoin isn't illegal. Laundering money is. Receiving coins that were used in illegal activity says nothing; you do that every day when you go to the supermarket.
