We cannot equate the commodity gold and bitcoin, because their own nature is not the same. The principal of the gold commodity itself is more likely to be a security investment and the price of gold itself is more stable because many factors help gold why its movement is more stable.
In contrast to bitcoin which tends to experience high fluctuations, we just need to expose it, if we want to invest safely, we can use gold, but with not a large profit or bitcoin with profits that can be expected to develop faster with high profits.
