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.
Actually you can't compare those two because first of all they are differ from each other. Gold has been widely used from past uptil now so it is impossible for bitcoin to surpass this one. Bitcoin is much better for being an asset for trading and investment like gold but not exactly. Crypto is much better to be used in online transaction and gold for physical transaction.
