So Bitcoin is better than Gold? 
Its value is higher than gold but I think if it talks about gold futures it is more stable than bitcoin. You can not be sure that bitcoin can exist in the next few years, but gold can still exist.People cannot earn gold literally because it was very hard to get and its not possible for everyone. Bitcoin is a lot easier and the only requirement that you have is a device that can connect to the internet. Maybe in the future, gold will lost its value and bitcoin will dominate the entire world since crypto currency is easier and too main stream.
