Is limited supply money such as Bitcoin better over the current forms of money?
For they can be printed out more (EURO, USD etc currency) and gold can be found all over the universe.
In a way Yes. High demand and less supply lift the price up but its not the reason why bitcoin is being used. EURO, USD and all others will still be used but its not that easy to print them out, there are requirements before they do that else the printed money will have less purchasing power. Bitcoin doesn't need this requirements but the blockchain technology where miners mine and us who uses the digital asset.
