I'm no expert, but crypto seems to me like it has wayyyy more room to grow. I'm not sure if there is even room to grow for gold.
If you look at the past 5 years of Bitcoin's price and th epast 5 years of an oz. or Gold's price you'll see a huge difference in the trends.
Gold is going up and down, the large dips in bitcoin are barely noticeable on a 5 year graph, what you do notice is a net rise in price and I believe this will continue for a while, the market is far from saturated.
