Many people owns golds. Gold used for many centuries as their currency. But bitcoin is beats gold. Imagine, there are only few people who is actually owns bitcoin. What more if the all peole use bitcoin? But gold is good to hold for a very long time since its value is stable. Bitcoin is good for short term investment.
It is much easier to use bitcoin. I used bitcoin to buy things, but never used gold.
You are right we can buy many things with bitcoins not with gold but we can keep gold for long term in purpose of good profit currently both giving good profit but for short term I like to hold bitcoin and for long purpose now both can work but still gold is much better option
