Numbers don't lie indeed but this will depnd on your risk appetite as an investor. High risk means high rewards and this is the bottomline here. If you're an early investor of Bitcoin and you managed to hold it for years, or for this long, then for sure you are in huge profit. If you are after real estate investment, there are other ways to increase the projected profit. Perhaps having a condo unit and making it an Air BNB, which do you think will earn more? However capital would be bigger in this case but if it is consistency then this could be an option. With Gold, you could increase the value by physical reformation through accessories and such.

My point here is that you don't have to be one-sided with how you will make use of an investment. Either of these three would be a great choice however, investments aren't always a waiting game. If you're seeking for more then you simply have control of other aspects that could increase the gain you want to project. Again, risk appetite is the answer on which should you invest your money with, as well as your circumstances as an investor.
