Never.... BTC cannot be used physically for anything. Gold will still be there if computers, technology fail.. Nothing will ever replace gold, has been there for a tangible currency for thousands of years...
I disagree vehemently. The only reason gold gained credibility is because they had the most number of users in the historical days.
There is nothing intrinsic about gold which holds any value except that it has some properties as a heavy metal. I could argue that my GPU has heavy metal properties.
All the gold bugs on this thread are just dealing with the realization that their penchant for gold is just based on history and past social proof not anything provably substantive.
