huge advantage to the gold side is stable price
huge advantage to the bitcoin side is prospects
But my choise is gold, i don't think that btc will cost more then gold (for a long time)
Gold has a very long history of survival during many financial crisis and in this long run gold surely will give a very good profits. But it's prices moves very slow and study so one has to wait for very long time to see some good profits. Bitcoin prices are very volatile and it can move both sides very fast. Every one is just thinking prices may go very high in near future so it is better to invest in both to take the advantages.
bitcoin prices are fluctuate so you can gain more profits for short term investment that you can choose
but for long term, i think gold is the best. that gold prices rise stagnate from time to time
I think people chose gold because they want invest for long term because the price usually stable. not like bitcoin, as you said the prices are fluctuate. It's good for short term investment.
