So many people have claimed this before. Highly unlikely. Both have their place in portfolios, to disregard golds history is a big mistake.
I agree with you. And it is completely wrong to say that gold has been defeated by Bitcoin. Even now, the market capitalization of gold is almost 100 times that of Bitcoin. And even the daily trade volumes of gold is much higher than that of Bitcoin. BTC doesn't even have a well defined derivatives market.
