Gold and Bitcoin are different things if you choose assets that will go up every year it is definitely gold and gold. considering the price of Bitcoin is not stable. maybe if you buy bitcoin, of course, you can get instant profit when Bitcoin goes up, only we never know when the price of Bitcoin will rise from the rate that you buy now.
Gold and bitcoin both giving profit for every one buy and invest, but bitcoin can get profit more than 10% just one day and need more than one year to get much profit with gold, just you can get lost with investing in bitcoin more than 10% after bitcoin have lower price just few hour later, I like investing with bitcoin than gold because I want become rich faster.
