Why not we have stop talking bitcoin is better than gold, look how much profit you can take by holding gold for one month and try for holding or invest your money at bitcoin, you can see more profitable holding or invest at bitcoin than gold.
In 2017 holding bitcoin is more profitable than gold, because the profits obtained are very large. But 2018 is better at holding gold because the price of bitcoin has dropped dramatically. For 2019, in my opinion, it is better for bitcoin investment, because prices will rise so that the profits obtained are greater than gold investments. Because the increase in gold is very little, so it does not appeal to speculators.
