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.
I agree bitcoin is under estimated to those outside the game, but Not sure how you can compare it to gold, a physical commodity... Is X footballer better than Y rugby player? Who knows.
