Yes, I think Bitcoin is more useful than gold, for example :
in transactions Bitcoin more simple than gold, Using Bitcoin all people can make a transactions only 1-5 minute.
Bitcoin simple, secure and fast than gold
Bitcoin can not be compared with gold. These are completely disparate things. You can not say that bitcoin is faster than gold, it's stupid. Gold is not comparable to anything, gold is gold. It was and always is a great value. This is one of the most stable values. Bitcoin has appeared until recently and what will be its value in 10 to 20 years is unknown.
