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.
Its easy to say that terrorists and other dark forces use Bitcoin. but it is actually one of the dumbest way to leave a footprint, and for ever.. all records of transactions are hashed into the block... fiat and gold on the other hand are the opposite (no records)
so lets educate people who say terrorists use bitcoin, they are smart enough to know not to use it anymore since the governments across the world have started watching it closely
