i think bitcoin more beneficial than gold because bitcoin increasing its price quickly than gold.
i agree with you and you are right that bitcoin is much more beneficial than gold, because bitcoin increasing its price too much faster and you can hold your bitcoin for high price for short time and gold price move to up very much slowly so bitcoin is better than gold.
but the importance of gold cannot be ignore, gold is so stable as compare to bitcoin and therefore most people use it to keep their investment safe. although it cannot give you a good profit that bitcoin can give but still gold is more reliable and trusted for keeping money safe.
