I believe that bitcoin is underestimated, I do not claim that it should only grow! But I'm sure that the future is for him! crypto currency in general, and bitcoin in particular - this is digital gold, many people still do not understand this. I'm sure that in ten years it will be so.
What makes you think many people do not understand what bitcoin is? There are lots of people in the world that knows about Bitcoin. The problem with some. Of you is that you think that bitcoin is everyhting while it is not. Bitcoin is an asset that can be owned, and you invest in it. Yes it is also money but it is not a currency (don't mind the currency in its name). So stop thinking that it will take over everything or whatsoever you are thinking that is going to happen in future because that's never going to happen.
You are right, crypto currency is famous all around the world and if we talk about bitcoin then there is no doubt it is the best invention ever,. Very soon all over the world there will be only bitcoin use to buy goods, even now we can see people are not agree to invest in anything else but only bitcoin, I personally believe gold will be no more with us as an investment in future.
