I think that the best option to invest at current point of time is bitcoin because I think in 2016 it has give 70% of return which no other asset class has given it. Also gold has not given anywhere that much return in past 5 years.
With gold you have to keep in mind that people use it as a very long term store of value solution and not really as an investment. People holding gold don't mind the price not going up a lot as they just add value to the stability aspect. If they at the end of a few years see that they gained like 10-15% then it's a more than welcome bonus for them. And people in Bitcoin constantly complain about Bitcoin not moving much while it has nearly doubled in value in the last 12 months
Gold as a personal long-term store of value has lost much of its shine long ago
Though it is still interesting as a short-term asset for speculation (you don't need to buy and sell physical gold if you aim specifically at that), I don't think that anyone with their eyes open and brain functioning (gold bugs obviously drop out from this category since they are mostly braindead overall) would consider 10-15% gain after 3-5 years as a "bonus" since this is where inflation would be for that time span, if not above (we are talking about US dollars obviously)
