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.
We have to put good proportion, but we have to be wise, butcoin is good for investment but it also risky to being hacked. It is fine to hold 10 - 20 bitcoin, but the most of the wealth is in gold. That is my oppinion.
