Out of thousands of cryptocurrencies or digital assets, biotin is considered the most profitable and productive cryptographic asset, based on distributed ledger system or blockchain. There is no competition for bitcoin in the entire crypto market regarding price and design. Visit to start trading in bitcoin. Developers initially discovered Bitcoin with the sole motive of replacing the centralized power of government money with a decentralized system of cryptocurrencies.

You can use bitcoin for numerous purposes; investing assets, transferring value, etc. Generally, international payment through bitcoin is considered one of the best ways because there is no involvement of government or any other legal authority in these types of transactions. It is the foremost reason BTC is a type of free-flow currency. In addition, you might know that bitcoin consumes power from a cryptographic system for technical operations. It is a fact that the craze of digital currencies, especially bitcoin, is at its peak nowadays.

So, more and more people are shifting their interest from real-life currencies to these virtual types of assets. However, bitcoin is highly volatile because of limited supply and heavy demand. You might be familiar with what will happen once the mining limit of 21 million bitcoin reaches. Below mentioned is a brief discussion regarding this topic.

Key Terms

The maximum number of bitcoins which miners from the entire bitcoin network can mine is 21 million.

There is a use of a rounding operator in the bitcoin codebase, making it impossible to reach the mining number of 21 million.

Once the highest possible number of bitcoin mining is reached, miners’ only remaining income source will be the transaction fee.


As mentioned earlier, the supply of bitcoin is limited to 21 million bitcoin because of its design. However, most crypto investors consider bitcoin digital gold because of its characteristics and nature. For example, it is a fact that new bitcoins are added into circulation every 10 minutes. The supposed time is 10 minutes because it is the exact average time consumed by every miner to create a new block.

According to the concept of bitcoin halving, the amount of bitcoin produced through mining will be reduced by the blockchain network to half after every four years in which approximately 2,10,000 new blocks are created. As discussed ahead, the only and most prominent reason for this fixed limit of mining is the use of arithmetic or bitshift operators. The primary role of these arithmetic operators is to round off the decimal points or number of bitcoin to the closest integers. This procedure is conducted only at the time of bitcoin halving because the new amount after halving is calculated.

They show these rewards in the form of satoshi because it is one of the minor units in the entire bitcoin network. The approximate value of a satoshi is 0.00000001 BTC. The most exciting factor is that the value of a satoshi can’t get reduced to half in the bitcoin blockchain. In simple terms, rounding off is the primary reason for the mentioned question.

Will the number of bitcoin ever reach exact 21 million?

It is impossible to reach the same 21 million bitcoin because of the rounding off procedure. Therefore, bitcoin for mining is constantly reduced to half of the amount. This procedure is known as bitcoin mining, and due to this procedure, the last bitcoin will get mined in 2140. Initially, the number of bitcoin offered to miners was 50, but today, it is only 6.25. You might be surprised to know that people have permanently lost approximately 15% to 20% of their bitcoin because they cannot find their keys to wallets.


No new bitcoin will be issued once the maximum amount of BTC gets mined, which will not exact 21 million in numbers. Miner will do the same work of validating the transaction for creating new blocks, but they will only get transaction fees in the form of income.

After reaching its peak, BTC will mainly be used as a store of value instead of using it for day to day transactions. At that time, miners will begin to charge a high amount of transaction fees because it will be their only income source. Therefore, the end impact of bitcoin can be harmful and positive after reaching its limits.
