At present situation government actually not so much concern about such kind of currency for that reason people are not so much interested for using this currency. it is now use as a electronic currency though computerized system.
in terms of purchase and sales bit coin holder's are safe but the lack of proper monitoring system by implementing different protocols client are demotivated for using this currency on investment projects.Every country's government should established a policy for securing those client who are holder of bitcoin like an cash or deposit account holders and this types of policy help to motivated bitcoin holders for investing different sector for establishing new entrepreneur in order to development of economical condition.
Making investment bitcoin was somehow a good and safe investment if you are just going to invest a part of your money because even if bitcoin can make our money or capital multiply into numbers, we cannot still deny and hide the fact that putting up all your money into bitcoin is still kinda risky in a way that it is still generated and operated online so it can also experience and cater kind of failure and malfunctions upon operating. It is a good investment but if you will make all your money into bitcoin, I think being a safe and good investment will be also a bad one once risk come into life.
