Normally I would prefer gold over bitcoin but gold is overfed already. It only gets pumped in extreme occasions like world war. Bitcoin is super young comparing to gold. It means, unlike gold there is much more room for bitcoin to grow.
Gold will always be relevant and more reliable than bitcoin, because it can be sold even without the Internet. But quickly earn better on bitcoin.
but gold investment is very low profit
and need very long time can get profit, you can compare return bitcoin and gold
