What Happens When the 21,000,000th Bitcoin is Mined?

Each Bitcoin has a supply of 21 million units. It’s done. By the year 2140, when the whole collection is mined, no more Bitcoins will be created. There are only a limited amount of new Bitcoins that may be mined each year until there are 21 million Bitcoins in existence on the Bitcoin network. Bitcoin’s network will primarily function as it does today once all 21 million BTC have been mined, but with one crucial change that will affect miners.

When Will The Last Bitcoin Be Mined?

An average of one new Bitcoin block is discovered and added to the blockchain every 10 minutes, thanks to the efforts of Bitcoin miners who must solve a complex cryptographic problem. Transactions in this block were previously held in the Bitcoin memory pool and were selected according to the magnitude of the transaction fee they pay to the miners for inclusion in the next block. The miner receives a predetermined Bitcoin block reward for finding a new partnership. The prize was initially set at 50 BTC; however, after finding 210,000 blocks, we reduced it to 25 BTC. As a result, the incentive is reduced to 25 bitcoins; 12.5 bitcoins; 6.25 bitcoins; and so on. 

What Happens When All Bitcoins Are Mined?

Miners’ primary motivation for serving as verifying nodes is in Bitcoin payouts. Satoshi has already solved the problem in the Bitcoin announcement release. It has already been stated that the incentive system may be replaced with transaction fees whenever the supply runs out.

Concerns Around Network Security

Bitcoin’s blockchain security may be estimated by looking at the overall amount of mining on the network, as indicated by the hash rate. Miners’ income and Bitcoin’s security risk when block subsidies decline. Several variables combine to keep Bitcoin mining profitable while ensuring its security despite the halving.

Charges for Transactions

First, the block subsidy — the freshly created bitcoin — and the total transaction fees paid in a block make up miner revenue. The term “block reward” refers to the value of this award. Because transaction costs aren’t halved, the block reward falls by a smaller percentage than half. Fees are projected to climb in the future as Bitcoin use expands, as demand for transactions on the network increases. That’s because every 10 minutes, we may verify only a specific number of transactions. To ensure that their transactions are confirmed on time, transactors must place a bid.


To begin with, the Bitcoin mining equipment itself is becoming better and better all the time. It was approximately 2013 when ASICs first appeared, the specialized microchips used by miners to maximize efficiency. If a miner improves energy efficiency and cuts expenses, it can mitigate an additional amount of revenue lost due to halving.


Thirdly, while energy costs change over time and space, the cost of energy—the most prominent component of a miner’s operational expenses—is typically decreasing. Energy prices fluctuate. A miner must be able to cut their energy expenses. As a reminder, miners often don’t pay the retail cost for electricity. Typical mining enterprises can deal directly with energy providers to obtain the lowest feasible price for their electricity needs. A Bitcoin miner can choose to site their operations wherever the lowest energy is available, making Bitcoin mining a truly global endeavor. For example, a mine can be located near an oil field or a hydroelectric dam, where other businesses are not permitted.

Tolerances for Difficulty

For the fourth time in this article, Bitcoin’s difficulty adjustment mechanism affects a miner’s predicted earnings. To put it another way: If the halving results in the closure of other miners, those that remain successful should experience an increase in profits since their part of the overall hash rate has grown. The difficulty of mining decreases as the total hash rate decreases. As long as miners keep going, a halving can help them earn more money by eliminating competition and boosting their chances of identifying blocks and collecting the reward, which is a significant factor in profitability.

Rewarding Transactions with Bitcoin Transaction Fees

Bitcoin’s miners will always be a reason to keep supporting the network even if the supply runs out. In addition to Bitcoins, miners already get transaction fees. Only about 6% of a miner’s earnings come from transaction fees. However, before Bitcoin’s supply limit is reached, transaction fee returns will likely rise dramatically. Before the last Bitcoin is mined, transaction fees will most likely gradually replace the current incentive for miners to sustain the network.

What Will Happen If No One Mines Bitcoin Anymore?

While some believe transaction fees will continue to be an effective means of motivating miners in the future, this is not universally accepted. It would permanently alter the Bitcoin network if most miners—or perhaps all miners—stopped mining Bitcoin. However, mining is required for the confirmation of new transactions. It would be challenging to spend Bitcoin in the future if the mining community stopped creating blocks. It is a dire warning for the Bitcoin network, but many feel miners will continue to mine even if transaction fees become the only payment. #Hashed’s Simon Kim told Decrypt that even if block incentives end, there may be adjustments in the future that might keep miners motivated, but not everyone agrees.
