Obviously the supply and demand law. If the supply us nearly breathing or many users buy bitcoin people adopting it the bitcoin price will surely reach the pick price of it because the supply will lessen extremely so the price will go up and up and if many user sell the bitcoin or stakeholder sell the bitcoin the price will dump that ut is how it works so for the bigtime and bitcoin millionaire they can control the market price easily but so far I think there's no one for now. Soif people invest we are lucky for the price to go up.
