Ownership of virtual currency is very risky and full of speculation because there is no authority responsible, there is no official administrator.
Without regulators, the use of virtual money is also prone to be used as a means of money laundering and financing of terrorism, so that it can affect the stability of the financial system and harm the public.
If in my country, the Indonesian bank insists that virtual currency including bitcoin is not recognized as a valid payment instrument. Therefore, its use is prohibited to be used as a means of payment in Indonesia.
But if for investment and to get additional income, I really support it, because I think only a few people who use bitcoin for crime.
