The #dropgold ad I watched is a little silly. Silly people in Armanis running like they've never actually run in real life. I tell you, if someone gave me a cart of gold bars I'd take it instead of going to Grayscale to "buy Bitcoin" only so that they can "take care of it for me".
Their campaign is going a bit too far in my opinion. Gold and Bitcoin can coexist together, and in fact lots of people that I know 'invested' in both of them.
They should frame it as "own gold and crypto together for your future" instead.
Of course, gold has always been and will be an eternal value and will not disappear anywhere. You cannot say exactly what will happen to cryptocurrency in 20-30 years, but you can definitely say that gold will exist in a hundred, and in a thousand years. Cryptocurrency will not force out anything, it will go along with the usual cash and non-cash currency.
