What is the long-term impact of Bitcoin's supply changes on its price? Bitcoin’s fixed supply of 21 million coins, combined with its halving events every four years, reduces the rate of new coin issuance. This scarcity mechanism, designed by Satoshi Nakamoto, aims to mimic precious metals like gold. As supply growth slows—halvings cut miner rewards from 50 BTC in 2009 to 3.125 BTC today—demand becomes the key price driver. Historical data shows price surges often follow halvings, like the 2020 halving preceding the 2021 bull run. However, long-term effects depend on adoption, macroeconomic factors, and market sentiment. If demand rises with limited supply, prices could soar; if it stalls, scarcity alone may not suffice. Bitcoin’s price reflects a delicate balance of programmed rarity and human behavior, making its future both predictable and uncertain.
