I think they go for the historical and gold drives up faster than you can say "grandma that hurt's"!
Gold translates better on a day to day as opposed to telling some one they just need to wait on downloading that blockchain and then giving them bitcoin in exchange.
Gold is indeed still the safe haven place where people like to store their money in times of crisis and other bad economical situations, but Bitcoin is perfectly capable of doing exactly the same. Both (where I personally prefer Bitcoin) are fantastic store of value tools, I just hope people will realize this too, and not only look at Gold.
Gold is more secure in compared to bitcoin because its more stable in terms of value because the price of gold stays stable for a longer time than bitcoin, while bitcoin is better in terms of profits as the price of it keeps growing with the time which can generate profits to the investors in a shorter time than gold.
In terms of profits and short trades we could make more on bitcoin compared to gold but you could somehow assure huge profits on gold on long terms same also in bitcoin. If you do have enough money to invest both then it would be the best idea to have both since they have the potential to make you more money in upcoming years.
