I truly believe that Bitcoin was adopting the law of the demand since it was already popularized by all people around the world nowadays, as the demand rises, the price of Bitcoin do also rises which makes its price expensive, attracting more potential investors to get into their investments with Bitcoin which makes it a lot more possible to make the price rise over time. It also do happen to balance the amount of demand with regards to the supply Bitcoin has so that we are still into control with the total amount consumption limiting everyone to drain off the total circulating Bitcoin.
