I Would go with bitcoin only, There is no matter what might happen in the short term, bitcoin is going to massively rise in the long term.
How much growth can you realistically expect from gold in 5 years? 10-50%?
With Bitcoin you get the opportunity to see your money at least more than double from the price right now.
That's why I will also choose for Bitcoin as being the main investment tool for me.
Bitcoin is the best choice to make an investment at a moment, and it is expected that price will skyrocket in future which can give us best profits in compare to gold.
