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.
Bitcoin already surpass gold, that's obvious. I know people who sell their bitcoins to buy gold and the lose tons of money with that stupid investment.
I don't know what's the market capitalization of gold, but for sure bitcoin can fight vs that.
