What happens when all 21 Million Bitcoins are mined?

Experts appear to be unsure of how Bitcoin (BTC) mining will turn out in 2023 given the ongoing global uncertainty surrounding cryptocurrencies. It is anticipated that in 2023, competition in the crypto market for electricity and environmental friendliness will increase.

Like a lot of other digital assets, Bitcoin was made with the idea that there is a limited amount of it. This means that Satoshi Nakamoto (founder of bitcoin) has set a fixed limit on how many Bitcoins can ever exist.

He put a cap on the number of Bitcoins at exactly 21 million. This number is different for other digital assets.

For example, Ripple’s XRP has a fixed supply of 100 billion, but Monero’s (XMR) fixed supply is much lower at 18.9 million.

The fixed supply of 21 million Bitcoins, one of the most notorious circulation hard caps, is a common example. This hard cap was a key element of tokenomics when it was created in 2009. Since then, 90% of all Bitcoin has already been mined.

Many people are also concerned about what will happen to the Bitcoin infrastructure once all 21 million BTC have been mined as we get closer to the cap.

What is Crypto Mining?

Crypto mining is the process of producing new digital “coins,” to put it simply. But that is the extent of simplicity. To mine these coins, it is necessary to solve challenging puzzles, authenticate cryptocurrency transactions on a blockchain network, and add them to a distributed ledger.

Bitcoin Mining

The process by which Bitcoin transactions are digitally verified on the Bitcoin network and added to the blockchain ledger is known as mining. To verify blocks of transactions that are updated on the decentralized blockchain ledger, complex cryptographic hash puzzles must be solved.

These puzzles require sophisticated tools and powerful computing power to solve. In exchange, miners receive Bitcoin, which is then put into circulation and gives the activity its name.

Now, How Does Bitcoin Mining Work?

Let’s explore the mining procedure step by step:

Configuring Strong Hardware Resources:

Before a miner can start minting Bitcoins, they must set up their rigs in terms of potent computing power and other specialized tools to effectively solve the challenging puzzles.

For effective and efficient mining, they would need either field programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), or graphics processing units (GPUs) with advanced graphic cards.

The most cutting-edge hardware available today is ASIC-based computers, and they can generate a huge number of hashes per second. But the price of such sophisticated equipment can be thousands of dollars.

Installing E-Wallets and Mining Software:

Miners need specialized software like CG miner, XMR miner, and multimineral in addition to powerful hardware requirements. Many of these programs can be downloaded for free and work on both Windows and Mac computers. 

You are now prepared to start mining bitcoins once the required hardware is connected to the software.

To store their rewards as Bitcoins, the miner would also need an e-wallet. A bitcoin wallet is a platform for storing, sending, and accepting bitcoin and other cryptocurrencies online.

Mining Pool or Solo Mining:

The choice between solo mining and pool mining is up to the miner. Mining pools were developed because mining alone is not all that simple. A mining pool is formed when several miners band together to face the increasing difficulty of mining. The miner’s share of the work is compensated.

The efficiency of mining Bitcoins in a pool with shared processing power also encourages mining that is less difficult to solve a block. Additionally, even though they will only receive a portion of the reward, this encourages small miners to participate to have a chance to make Bitcoin.

How Many Bitcoins Have Been Mined?

As of January 29, 2023, 19.27 million bitcoins were in circulation. Before the 21 million bitcoin cap is reached, there are currently 1.73 million bitcoins that need to be mined. 

How Long Does It Take to Mine One Bitcoin?

The amount of the block reward, or how many new bitcoins are given to crypto miners for creating a new block, determines how long it takes to mine one bitcoin. As of now, the block reward is 6.25 bitcoins, and a new block is generated every 10 minutes or so. A new bitcoin is thus created roughly every 0.625 minutes.

Will the Number of Bitcoins Ever Reach 21 Million?

The total number of bitcoins that will be made isn’t expected to reach 21 million. This is because the Bitcoin network uses bit-shift operators, which are math operations that round some decimal points down to the next smallest integer.

This happens when the block reward for making a new Bitcoin block is cut in half and the new reward amount is figured out. One satoshi is equal to 0.00000001 bitcoins.

As a satoshi is the smallest unit of measure in the Bitcoin network, it can’t be cut in half. When asked to divide a satoshi in half to figure out a new reward amount, the Bitcoin blockchain is set up to round down to the nearest whole number using bit-shift operators.

Because Bitcoin block rewards are rounded down in small amounts of satoshis, the total number of bitcoins that will be made is likely to be a little less than 21 million.

Since the number of new bitcoins issued per block drops by about half every four years, the last bitcoin probably won’t be made until the year 2140.

What will be the Effects of Finite Supply on Miners?

To mine bitcoin, miners need expensive computing equipment. Currently, the majority of miners and mining companies use the block reward to cover their costs and turn a profit.

The cost of maintaining the mining operation, however, will eventually outweigh the rewards earned by the miners as mining rewards are halved every four years.

This might take place even before the fixed supply is exhausted. However, a decline in block rewards should be partially offset over time if the price of bitcoin rises. The only issue is what transpires after all the coins have been mined.

In theory, if a miner validates sufficient numbers of transactions, the fees collected could assist in making up for the lack of block rewards. However, the amount of the transaction fee will change based on the network’s condition in the future.

There are only 21 million Bitcoins available, and it is unclear how reaching this number will affect the price of the virtual currency. When this limit is reached, the mining reward is eliminated, which might deter miners from continuing. The network might then become less secure as a result, which would harm sentiment and drive down prices.

At the same time, as Bitcoin’s supply reaches its maximum, its value might increase. Any rise in demand would drive prices higher once the supply was fixed. Furthermore, reaching a hard limit on the total number of bitcoins available might amplify the idea that the virtual currency is in short supply, which might lead to an increase in price.


What Happens When All 21 Million Bitcoin are Mined?

No one is sure of the answer, so there is a lot of talk about it. But experts say that once all the bitcoins have been mined, no more will be made. Bitcoin transactions will still be grouped into blocks and processed, and Bitcoin miners will still get paid, but probably only in the form of transaction fees.

What Happens to Mining Fees When Bitcoin’s Supply Limit Is Reached?

When there are 21 million Bitcoins in circulation, mining fees will go away. After that, miners will probably only get paid for processing transactions instead of getting both block rewards and transaction fees.

How Profitable Is It to Mine for Bitcoins?

As with any other type of investment, if you want high returns, you have to take on high risks. Those who can afford the best mining equipment or contracts can make money by mining and trading bitcoins.

But if you are a small-scale miner who wants to bring home a lot of money, you may need to adjust your expectations. This is important, especially as more miners and institutional investors join the group.
