I dont think we need even more reasons when the most basic of the reasons is already there, we can profit from it, whether you want to hold short term or you are in for the long term holding gold, silver and bitcoin is a good choice, hold the one you like the most but hold some and you will be fine.
It is not only about profiting from the trend but with the recent situation and global scenarios a war is looming above us with North Korea showing their strength and carrying on their missile test so,if there is a war then gold will be the most valuable asset without a doubt and i am not sure where bitcoin stands in times of war.
