Actually, there are no laws regulating bitcoin in Argentina. It is perfectly legal to mine, buy, sell, or trade BTC.
We are not a communist country, and from the way it looks, it is going to stay that way. It is in the U.S. that bitcoin traders have to worry. The U.S. is scared of Bitcoin and they will regulate it soon more than likely. People have already been charged for trading in bitcoin without a license in FL. CA requires a license now and other states want to start regulating it.
