While the cost of Bitcoin mining can be very high, the return on investment (ROI) is even higher in key operations with huge mining capabilities.
Solo crypto investors must therefore understand how mining works before diving into this world. This guide will explain the difficulty of Bitcoin (BTC) mining, one of the most common terms in mining. What is it and what is its advantage?
What is the difficulty of BTC mining?
The difficulty of BTC mining is a measure of the complexity of mining BTC. It shows how difficult it is for the average miner to examine blockchain transactions and acquire new BTC.
As mentioned above, BTC mining is a long process that involves solving very complex cryptographic equations. When mining is very difficult, miners use very high computing power to successfully resolve cryptographic equations and full transaction validation. The opposite is also true.
Many experts believe mining should be quite difficult to protect your network. Crypto-blockchains with ultra-high mining difficulty similar to BTC are extremely secure.
BTC uses mining difficulty to stabilize the average time between blocks as the network hash power changes.
One thing to note is that the difficulty of mining is a protection parameter only for the Proof of Work Blockchain. This is because it is only the POW blockchain that miners perform auditory functions that prevent fraud and validate available transactions. The difficulty of mining POWs essentially controls the time it took to complete a new block.

Why are cryptocurrencies mined?
Fiat currency relies on printing. Central banks such as the Federal Reserve and the European Central Bank can stir up more papers at any time.
Cryptocurrency has its own unique problem. Remember the part where the central entity is not supposed to manage publishing? Yes, the option to issue central agency issues is not possible. Therefore, Nakamoto Atoshi has created an independent system that issues new coins.
Powerful computers help protect the network by checking transactions, and issue new coins to make blocks added to the blockchain successful. The process is called mining and is an essential aspect of decentralization.
What is the relevance of BTC mining difficulty?
So why is it difficult to mining codes? There are basically two advantages to the difficulty of BTC mining, including:
- Network Stability
- Network Security
- deflationary btc value
Network Stability
One of the main professionals related to mining difficulty is network stability. The BTC blockchain completes a new block every 10 minutes. Without the concept of mining difficulty, it is difficult to maintain the stability of the block emission period. Therefore, the difficulty of mining ensures that the 10-minute block creation cycle is stable.
But why do networks autonomously increase or decrease the difficulty of mining? The number of miners in the network at a particular time will encourage changes in the difficulty of mining.
For example, consider a situation where many miners are fighting simultaneously to mine BTC. In that case, the BTC network increases the difficulty of mining. The idea is to make mining coins difficult, so maintain stability for a period of 10 minutes to free the blocks.
If there are few miners, the network autonomously reduces difficulty. This reduction will help a small number of miners complete the block within 10 minutes. The difficulty of BTC mining does not guarantee unpredictable overflow of new BTCs during circulation.
Long-term deflationary btc values
The difficulty of BTC mining also helps to ensure that BTC value is deflationary in the long term. As mentioned above, difficulties eliminate the unpredictability of the low novel BTC in circulation. As BTC is expected to be released, it will not affect the price of the coins in exchange.
Network Security
Network security is another advantage of the difficulty of BTC mining and associated adjustments. Blockchain networks are susceptible to attacks from bad actors, including miners. The problems such as 51% of attacks are primarily the result of network miners using the system.
The difficulty of BTC mining essentially increases the resources needed to mine assets. Increased resources means mining costs increase. By increasing resources, the network can bear massive losses if the miner fails, making it difficult to attack the system.
How do mining difficulties change?
As mentioned before, in order for the network to maintain stability, it is necessary to adjust the difficulty of mining. So how does the network adjust the difficulty of mining?
When mining, miners have target hash. The target hash in BTC is a specific fixed length code that contains several zeros before the code itself. He is considered the winner.
- Before the hash, you must generate equal or greater than zero code.
- You must be the first person to generate this code.
So, to prevent blocks from being discovered at super fast speeds, BTC has an algorithm that adds or reduces the number of zeros before the target hash. Adding zeros will harden the block discovery process while doing the opposite simplifies the block mining process. By making the mining process hard, the BTC network helps maintain the steadily increasing value of the coin.
How can you calculate the difficulty of mining?
Calculating the difficulty of BTC mining is another important factor to consider. How can miners know the difficulty of mining? There are many different formulas used today, but the most popular ones are:
Difficulty = Difficulty target/Current target.
where;
- The difficulty target is a hexadecimal table with a target hash with a mining difficulty of 1.
- Current target. The target hash of the most immediate block of a transaction.
Get an integer, or difficulty, each time you split the difficulty target with the current target. If the answer is obtained as 25 trillion, that is the difficulty of mining. This means you need to generate over 25 trillion hashs to get the winning hash. In some cases, miners are less guessing and can get the correct hash.
Adjusting the difficulty of mining
As mentioned before, the average time to release a single BTC block is 10 minutes. Difficulty adjustment compares the average time required to find 2016 blocks on the network and the time it took to get an immediate block for 2016. 2016 block intervals are epoch. After all eras, BTC networks calculate and readjust the mining difficulty.
The standard time required to min a 2016 block is 20160 minutes (2016 x 10 minutes). 20160 minutes is equivalent to two weeks of block production. Currently, the calculations to adjust the difficulty of mining are as follows:
20160 mins/actual time (epoch) used last year 2016 x latest difficulty = mining difficulty upward or downward change rate
If the percent change is positive for 300% (4x), the network is adjusted to 300% only. This +300% change was made on July 16, 2010 after the hashrate increased from 300 to 1300 mh/s in the previous epoch.
The change is only -75% (¼¼) on the negative aspects of all epochs. The minimum adjustment was -27.9% on July 3, 2021 after SICUAN closure. Limiting the rate of change at the top or downwards of mining difficulty confirms that there are no large sudden changes.
The epoch consists of 2016 blocks, but only the 2015 blocks are related to difficulty level calculations.
What happens if all BTC is mined?
So, once the BTC mining process is finished, what is the difficulty of BTC mining? Essentially, the idea of mining BTC after mining all 21 million coins can lose meaning.
However, transaction validation and network security are highly relevant to the ecosystem. Therefore, miners still need to participate to ensure that the BTC network is still running. In this case, the reward will be a trading fee, not a new coin.
The final words
This guide deeply explored the concept of difficulty in BTC mining and how to calculate it and adjust the prediction accordingly. As has been seriously repeated, the difficulty of BTC mining is the complexity associated with releasing new BTC into the circulation. This process in blockchain helps ensure BTC deflation value in the long term while maintaining the security and stability of the BTC network.

FAQ
What is Bitcoin Mining?
Bitcoin mining is the process by which a computer performs complex mathematical calculations to solve the encryption puzzle and create new BTCs. This process can be used to view transactions between two parties, confirm BTC payments, and create secure records.
How long does it take to mine Bitcoin?
Mining BTC is not like mining other cryptocurrencies such as Litecoin and Dogecoins. Each computer has a set amount of processing power used to solve the mathematical equations of new currency blocks added to the blockchain. The first person to solve the equation will be rewarded with a new coin, but all participants will receive some.
Mining difficulty increases with each block in 2016, making it increasingly difficult to find blocks. Therefore, miners need to upgrade their hardware regularly. If done correctly, this process should provide rewards proportional to how much effort it took to solve the problem. One BTC equals 10^9 bytes of information, and it takes about a minute to see the block. This means that the average check time is 10 minutes.
Is mining bitcoin difficult?
Recently, BTC mining has been challenging due to increased competition and increased demand for processing. With additional miners involved, the complexity of the process, which involves solving challenging mathematical problems, is adjusted to maintain a 10-minute block period.
Today, most people cannot mine from home because they need special ASIC equipment. Additionally, this process uses a lot of energy, and the cost of electricity has a major impact on profitability. With all that in mind, mining BTC is difficult and requires a lot of hardware and electricity spending.
Is Mining Bitcoin easier than mining in Ethereum?
Mining is no longer feasible on the Ethereum mainnet, but it is still feasible on the Ethereum (ETH) classic. ETH’s staking strategy uses much less energy than BTC mining. It uses a lot of power using ASIC technology. ETH staking is more accessible as it only requires 32 ETH or a staking pool, but BTC mining requires expensive equipment. ETH staking offers consistent benefits with operational risks, but BTC mining has a tremendous potential for revenue, but also considerable costs.
What causes the difficulty of mining?
The difficulty of mining blockchains fluctuates, with the main driver being the number of participating miners.
However, miners are profit-oriented and expect revenue from block rewards to offset resource expenditures. During the high priced period, mining difficulties are the most as more people are involved and even those with older equipment make profits again. Therefore, hashrates are also primarily influenced by the price of the coin.
In bull markets, the difficulty of network mining constantly increases as more miners connect and supplies hashrates. In response, the network mining algorithm readjusts the difficulty and increases it as the hashrate increases.
