Bitcoin’s Remarkable Journey: 20 Million Coins Mined
In an insightful update shared by the on-chain analytics firm Glassnode, Bitcoin has recently marked a significant achievement. Over 20 million tokens of its capped 21 million supply have now been successfully mined and are in circulation. Such growth in supply is attributed to miners who, upon adding a new block to the blockchain, receive a block reward. This reward system, however, is not static and experiences reductions over time through events known as Halvings.

The Dynamic of Bitcoin Halvings
Bitcoin debuted with a block reward of 50 BTC, but subsequent Halvings have reduced this reward to a mere 3.125 BTC. These Halving events occur approximately every four years, with the next anticipated around 2028. As the block reward diminishes, the expansion rate of Bitcoin’s supply also slows down. Ultimately, Bitcoin’s supply has a predetermined limit of 21 million tokens, beyond which no further block rewards will be distributed, ceasing the occurrence of Halving events.
Bitcoin’s Current Supply Milestone
Having now surpassed the 20 million mark, Bitcoin’s current circulating supply represents over 95% of its total possible supply. This milestone was achieved when block 940,000 was mined, taking the network approximately 17 years to reach this point. Glassnode provides an illustrative chart that positions this milestone within Bitcoin’s historical context of significant achievements.
Projected Timeline for Bitcoin’s Complete Supply
As Halving events continue, the pace at which the remaining 1 million tokens are mined will decelerate significantly. It is projected that this final segment of Bitcoin will not be fully mined until around the year 2140, making it a multi-century endeavor. This limited supply inherently means that miners will eventually see a cessation of block rewards, which are a major component of their revenue alongside transaction fees.
Miners’ Future Revenue: Transaction Fees
Upon reaching the 21 million cap, miners will rely entirely on transaction fees for income. Currently, these fees are insufficient to replace block rewards, leaving the future financial landscape for miners uncertain as we approach 2140.
