Many are saying that indeed bitcoin is just a bubble. Ofcourse those who don't believe in bitcoin will say that. However, whether it's a bubble or not, it is up to the person like you and me if we will believe in it and continuously invest. We all since then that investment requires risk as well. This can be a humor only unless bitcoin will continuously prove itself that it is not.
Yeah it is depends on what we believe ,if we think its a bubble then stop investing but for me its not a bubble ,many of us help by bitcoin and this is one of the reason why i still believe in bitcoin.
