Everyone will say scarcity is expensive, the gold is scarcity the same as the bitcoin.
I can't find the reason from the gold valuable.
It can't do anything worth thing...
Gold is internationally recognized as a measure of national value. Gold also has the use of jewelry. Gold is a metal that we can handle, touching them. Nowadays bitcoin is not common, some countries do not know bitcoin, some do not accept bitcoin. Although bitcoin prices are high, bitcoin has not served the needs of human life. So I think the value of bitcoin is not equal to the value of gold.
