Each government has their respective considerations in responding to the development of cryptocurrency. As good citizens, we must follow these rules. Well, before we have to learn well about the status of bitcoin (cryptocurrency) in our respective countries, there are some that fully forbid and some that only for certain sides, for example, may only be used as an investment or commodity trade, and restrictions given usually associated with payment systems. So, even though it is not regulated, it is permissible to trade and invest, and the exchanges available in my country are officially registered at the ministry that deals with trade.
So do not generalize and overdo it, it must be studied more deeply because bitcoin has also been well received in most countries even with high-risk status.
