Why do many people call Bitcoin "digital gold"?
The image of the logo displayed on Bitcoin resembles Gold, but not gold, the posture and shape resembles metal and is colored gold, but not gold, nowadays people don't want to bother in calling something, if the object resembles silver, gold, bronze they will say as they see it, to make it easier to pronounce and remember.
What you to know, Bitcoin is not physical, besides that Bitcoin can only be obtained when the internet is active, while real gold is in the bowels of the earth, does not need the internet and gold is physical, not imaginary, gold is a precious metal item, Bitcoin cannot be replaced as gold, that will not happen.
The nature of gold is unlimited and inexhaustible as long as the earth still exists, Bitcoin only has 21 million coins, if 21 million people in this world buy Bitcoin, Bitcoin will run out.
