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.
I read a very interesting article on that subject the name was "btc is not a bubble the btc and the needle". And it was magnificent how the author described some things that make us think.
Today the world bubble is the governments and banks that at any moment can destroy the world economy in a matter of days, inflate and deflate weekly and cause panic in several areas. The btc today and the needle that will pierce this bubble, will open a new path in the area of values.
