Well I don't know about that. Gold is a big business. In every town all over the world there is going to be pawn shops that will buy your gold. they not might not be interested in your bitcoin though.

Gold for some people serves as a status symbol. you can wear it and display it if you have enough money to buy a gold chain. or you can buy a gold bar and admire its beauty. you can't do that with a bitcoin. so no, i don't think people of this age all prefer bitcoin. there will always be gold collectors and people that wear gold as a status symbol. they won't care about btc at all. just how it is.
