Gold is the metal for long-term investment, but after the price rose up to the clouds it is not interesting to invest money. It is a bubble which will burst as well as collapsed real estate prices.
Gold is only for long term investment because the value not going to dump always increasing but your money will sleep or a long time. That is why i choose to invest in bitcoin because i want to earn fast as i can to have other investment like real state if i got lucky here.
Actually both are very profitable if used for investment but since bitcoin prices continue to rise and fluctuate better than gold, I prefer bitcoin for investment. If bitcoin prices are consistent and continue to rise this would be the best investment. So maybe true, bitcoin is the best investment and worth to choose, it's more profitable.
