TBH I think these guys who played into the scheme should lose their money as a lesson to what happens when you give your trust away to people who don't deserve it. But I'm just hardcore like that.
So, when someone is victim of a crime it's their fault and they should be punished for being scammed?
I already saw some similar schemes being discussed in this forum, Onecoin comes to mind.
Users should be more careful when they trust services like this, their money can instantly dissapear. IMO more regulations should happen regarding bitcoin/crypto currencies/virtual currencies etc to prevent events like these.
