I think holding gold and holding btc both are profitable. Because both value increase and fluctuates with time. Investing in either of them. Will benefit you. But talking about who will benefit more and more . I will say that bitcoin benefits more and more than the gold. Gold prices increases about 2-3% but bitcoin increase about double tripled in the same time span. Bitcoin is the first crypto currency and people are getting rich by investing in it. Best thing you can mine your own bitcoins. And it's prices are always increasing and with time it's is estimated that bitcoin will be used by the most of the population. So holding btc us better idea.
