We can't compare bitcoin and gold,But according to the value,surely overpass the gold value in near future 
It,s true, we can not compare bitcoin and gold. Both things are most valuable. Bitcoin is the number one currency. Without Bitcoin we can not imagine crypto. Gold is the most expensive metal. It has also a value. So both are different each other. Over passing is not the right thing. Bitcoin will grow like Bitcoin, Gold will grow like Gold. Both are very valuable .
