If you had to convert all your wealth to either Bitcoin or gold and keep it there for 10 years, which would you choose? Keep in mind the fact that Bitcoin has only been around for 5 years, and could be fundamentally different in any number of ways in 10 years.
I will choose to have bitcoin, After 5 years of holding I will cash it out and invest all of it in many different ways. Unlike golds or fiat money, bitcoin is volatile and cannot be affected by a countries economy.
Gold is $1300 per ounce approximately and this is showing it's stable compared to bitcoin, hence the return is very small in gold compared to bitcoin. Bitcoin gives better returns actually.
