Gold is not that better than Bitcoin but it is more popular and more used and thats it, but if you want to talk about the future than Bitcoin will be more used and that is nice for the currency itself.
And that is because the world is also becoming more digital and Bitcoin is digital money so that is perfect.
From aspect popularity obviously bitcoin is loses when bitcoin compared with gold. For the most of people gold more beautiful than bitcoin but, when we see the advantage of bitcoin we will more choose bitcoin then gold.
I know right. Noone would go in a supermarket and trade with gold ingots...
