Everyone will say scarcity is expensive, the gold is scarcity the same as the bitcoin.
not everyone is saying it!there has always been some comparison between bitcoin and gold because people love to compare things with each other even though they have nothing in common but i don't find that much similarity between bitcoin scarcity and gold's.
I can't find the reason from the gold valuable.
gold has been around for millions of years and has been used as a valuable for thousands of years and it has been even used as a currency for hundreds of years.bitcoin has been around for 9 years!
It can't do anything worth thing...
WHAT 
haha The price of bitcoin has exceeded of gold before.
here is an example of a bad comparison! how much gold? 1 bar of gold or 1 ounce?
how much bitcoin? 1 whole bitcoin or 1 bit (100 satoshi)?
you are comparing one of the smallest units of gold with one of the biggest units of bitcoin
