Lately, some people in some countries use bitcoin as a conventional exchange or a substitute for credit cards to make transactions. But keep in mind is so far no official status of the government about bitcoin. Whether it is legal and can be a digital currency in the future or still as it is today. If there is no certainty from the government it will be very dangerous because we will not know what will happen to bitcoin in the future.

Until now, there seems to be no government from any country that dares to declare legality of bitcoin, although they are aware that bitcoin is a great asset and beneficial to wider community. So sometimes there is anxiety about bitcoin for the future will be a digital currency and have a definite legality or vice versa.
