For me, Bitcoin...
I always choose the new thing, gold is a conventional investment tool, it's demand increasing but a decreasing rate, in the future, demand of gold will not be same as present. Bitcoin has created a new platform to make profit, it's value is increasing at a increasing rate so that i refer many closest person of me to invest in Bitcoin rather than gold.
Nope I think gold demand will also rise slowly to see the world's population also continues to rise. As long as it happens gold inventory on earth continues to decline and this is certainly a great potential for gold prices to rise high in the future later? You also have to calculate it
