I totally agree with it. Gold is one of the most accepted form of investment worldwide and also legal. So gold is a must have item if your portfolio. The price of gold is somewhat stable which ensures the capital protection. Even if you don't want to get profit from it, you can use gold to make ornaments for yourself.

On the other hand, bitcoin is a crypto currency which is liquid and dynamic in nature. Bitcoin investment can fetch you a lot of profit in a short period of time. Also the prices can go down in a very short period of time which can make your portfolio looks bad. So yes, Gold and bitcoin both are great asset of investment. Gold for capital protection and Bitcoin for long term profit.
