Bitcoin Hits 20 Million Mined: Less Than 1 Million Coins Left 

Bitcoin has reached a significant milestone, with over 20 million of its 21 million total coins now mined, meaning fewer than one million remain to be created. The remaining satoshis are projected to be mined around the year 2140 due to the programmed halving events that reduce mining rewards every four years. Currently, miners earn about 450 BTC daily, and they will increasingly depend on transaction fees as new coin issuance slows. Furthermore, the effective circulating supply is reduced because an estimated 2 to 3.5 million BTC may be permanently lost due to lost private keys or being unspendable by design, such as the coins from the genesis block. While Bitcoin's price remains volatile due to market sentiment, its fixed and transparent supply schedule reinforces its scarcity and "hard money" characteristics compared to traditional currencies.
