I think both have got investment appeal. Gold is tangible and traditionally has proven to be a hedge when the value of the dollar goes down. That said, the appeal of bitcoin is that investors/ traders alike find the phenomenal increase in “value” hard to resist. Who would not want to be putting their money into an “asset” class which increases 100-1000%in a very short time frame? The reason why we buy stocks as well is to make our money grow so any asset class which helps that will attract the masses.
