Gold has proven its worth for a long time and I don't think that is going to change in the near future. Wherever you go, gold is a relatively known commodity that commands a great value. To compare it with bitcoin which is still at its early stages of development would be a little off. We all know that both has value right now but bitcoin is pretty much still an unknown currency, that is to the general masses.
Yes, You are right . Gold is still a strongest assest until now. Almost people around the world keep gold for storage but bitcoin is newer with customers and it's not popular with all people in the world beside that bitcoin hasn't yet been accepted by the government .
