Owning bitcoin is not a crime. If you do something illegal with bitcoin, it will constitute a crime.
But some countries ban bitcoin because it is a decentralized currency and the government does not welcome it.
Yeah, because like money in general bitcoin is not a crime but is often used by certain parties to do evil things. But what I did not think, why the state always use reason bitcoin ilegal cause being used for unlawful activities. On the other hand, I think the government just does not want to lose if bitcoin legality in their country. Because the government can not get benefit with bitcoin legally in their country such as tax collection. Thank you.
