Just beware if government want to take your stuff for the "greater good"
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.
Some regulation is not a bad thing. It means the government has some acceptance of it. It's if a country goes after or ban's that is really bad.
If you are huge on LBC and trading in person.. yes you might get a money laundering charge. They normally hold this for bigger operations though like when Charlie Shrim got his felony. But exchanges are able to work in most states they just have to follow regulations.
