"They would get caught" get caught for what? since when stronger hash rate insert block first or double spend is illegal?
Are you talking about blockchain analyze or good/bad bitcoin filter shit again? this would kill bitcoin first you know?
I didn't say they would go to jail. But people are going to find out who minted the bad coin(s). It's not going to be good for their business and likely
will end their operation. It is also true that depending on where they live it
could be illegal. For example selling such coins may constitute
fraud in the U.S. Although it may be unrealistic to assume the police will help.
Personally I am against "colored" coins. However if we have a 51% attack I think we would have
such a system within months. I assume nobody wants counterfeit bitcoins.
Sorry but no, not gonna happen. It won't be called bitcoin anymore if these kind of shits really happen.
And there is no good/bad real/unreal bitcoin, they are all same tokens sha256 verified in main block or "fork" blocks. People("tough" bitcoiner kids on internet) might or might not find out who they are and they will be just fine on doing that as before.
