I would not say that gold is better then bitcoin or that bitcoin is better then gold because I only invest in bitcoin and I do not nothing about gold at all.
I hear that gold is stable for many times but it seems that bitcoin is also going to be that way.
but very honestly i will like to say that both are important for me, and both have their own value we cannot ignore the value of one and not can give preference to one on other.
Well for me both are good to invest but the problem gold is safe and it takes a long time before you can make a good profit if you have patience gold is a good investment and bitcoin you can see fast movement of the price so if you want trading fast bitcoin is a good choice..
Earning profits from bitcoins is not time consuming like gold as price volatility in bitcoin will allow you to make quick profits and in gold you need wait for a longer duration to make profits.
