Bitcoin approaching the 2140 milestone sounds like the end of mining, but it actually means the end of new coin issuance. The current circulating supply amount has reached nearly 20.05 million units. $BTCequivalent to 95.47% of Bitcoin’s fixed maximum value of 21 million, approximately 950,000 $BTC Still waiting for it to go into circulation. The strange reality is that even though almost all of Bitcoin already exists, it may take more than a century for the last bit to emerge. This unusual delay is due to a financial schedule designed to repeatedly delay issuance, rather than being stopped by a sudden and dramatic event for miners around the world over the next few decades.

Mining continues even after issuance ends
Bitcoin currently has approximately 3.125 issued $BTC The reward decreases every 10 minutes, but the reward is programmed to be cut in half approximately every four years. The next halving is expected in 2028, when the subsidy will drop to 1.5625. $BTC block by block. Systems built around predictable scarcity become increasingly difficult to visualize as the rewards shrink to the tiniest bit. There are reportedly around 90,995 blocks left before that event, putting Bitcoin more than halfway through its current cycle, but one estimate identifies April 13, 2028 as a potential date after a countdown of around 631 days from the current schedule.
Once the last Bitcoin is mined around 2140, block rewards from newly created coins will be lost, but miners are not expected to disappear. Currently, their revenue is a combination of block subsidies and transaction fees paid by sending users. $BTC. Therefore, the end of issuance changes Bitcoin’s security model rather than ending the mining process itself. Miners continue to verify blocks and protect the network, but their income depends entirely on fees. An open question is whether the deal can provide compensation to cover costs and keep mining profitable without the subsidies that have supported miners for generations.
Binance framed this transition as a result of Bitcoin’s supply cap, which remains central to its asset design. 950,000 remaining $BTC As the halving continues, the amount of issuance will be reduced and the process will span more than 100 years and will be distributed in stages. Bitcoin’s last mining era is more like a long economic handover than a cliff. Nothing dramatic should happen on the day the last part appears, but the incentive structure will complete its transformation. By then, miners will become dependent on fees submitted by users. $BTCnewly minted coins will not supplement the income after the block subsidy is permanently gone.
