Why is Bitcoin valuable?

Bitcoin is valuable because of scarcity, decentralization, and utility. Only 21 million Bitcoin will ever exist — new bitcoin supply is cut in half roughly every four years through the bitcoin halving. Bitcoin can be sent anywhere in the world, 24/7, without permission from any bank or government. Its growing bitcoin adoption by individuals, institutions, and nation-states reinforces bitcoin value as both a store of value and a medium of exchange.
