Both bitcoin and gold is a good investment, but gold is more stable and more suitable for a long term, while bitcoin is more suitable for short term, and real reason to hold bitcoin is to beat inflation, as we know if we invest our money in fiat then every year our investment value is going down but bitcoin wont be influence by inflation
yes that is a fact that gold is more stable than bitcoin. but if you are going to invest your money for profit then you should need to invest your money in bitcoin because the price of bitcoin is expected to increase therefore you can earn more money by investing in bitcoin rather than investing in gold, because gold has a very stable price and there can be a very slight increase in the price of bitcoin.
