that is the opinion of people, so it's okay if they think that Bitcoin is better than gold. to be honest, I thought so too, that Bitcoin is better than gold because the rise in Bitcoin valuations in the past 5 years is much faster than gold, so I don't think there is a problem if I consider Bitcoin better than gold 
in my opinion, bitcoin is no better than gold because the value of gold can be stable and the value of bitcoin can change at any time which will affect the selling value. I think bitcoin is good when bitcoin prices rise.
