Correct me if I'm wrong anybody, but I believe the IRS wants you to put digital cyrpto currencies under taxable income if you have any type of significant amount of Bitcoin. Still, many people do not do this. It's a light governmental regulation, but nonetheless, it's a regulation.
I think you already have to pay it to government however it's an anonymous coin, you can hide and be happy.
There's a lot of thing in bitcoin that government hate, they have no control about it.
It wasn't until around 2014(?) till they added the regulation into the tax code somewhere. I only heard about it until last year that some of the big Bitcoin companies pay huge taxes on their income. This would include individual people to put Bitcoins they own when they file their taxes. To your point though, many people don't report them.
