I'm just talking about bitcoins here. A Law On Bitcoins Stealing. Not on theft as general term. By the way, i'm from earth

I don't think so that there is already a law for each country that is covering the case of stealing of bitcoins. Even though stealing is illegal and crime.
But still there is no law for it and I think that will be long time before a law will be pass and consider that they will honor bitcoin.
And as of now, it is really sad that if you will be a victim of stealers, you can't do something about it.
