Gold doesn't have any surprise potential - everyone know about it, its properties, estimate supply, etc. Bitcoin is even better for storing value, because it's easy to move, obtain and store, unlike gold. Although being digital makes it reliable on electricity and Internet, which can make it bad in case of big war or other disaster. Bitcoin is obviously riskier than gold, but also comes with a very good portential to double in price in a few years, something that gold can't realistically achieve.
I would not have Bitcoin compare with gold. As you all know adults and other features and benefits, That's only in this regard, no one wants to talk. Of course, I will not argue about the future of Bitcoin because its price grows very quickly.
