How to mine Bitcoin: the complete guide to profitability 

What is bitcoin mining?

Bitcoin mining is the process by which transactions are verified and added to the public blockchainA blockchain is a type of distributed ledger technology. It is a huge database formed by blocks,cryptographically linked to each other, containing information such as transactions. These blocks are addedfollowing, the ledger that contains all past Bitcoin transactions. This process is essential for validating transactions and securing the network. 

Definition and operation  

Mining is carried out by nodes on the network, often referred to as “miners”. These miners solve complex mathematical problems to add a new block to the blockchain. In return, they are rewarded with newly created bitcoins and the transaction feesFees related to operations; they sometimes are distributed to miners. for the block they have solved. This is known as the “block reward”. 

Mining rewards 

The rewards are an incentive to encourage miners to devote their computing power to the network. Initially, the reward was 50 bitcoins per block, but it is halved every four years in an event called “halvingBitcoin protocol halving miners’ reward every four years.“. Today, the reward is 3.125 bitcoins.

Is it profitable to mine bitcoin in 2024?

The subject of the profitability of bitcoin mining is a crucial one for anyone considering embarking on this adventure. Bitcoin mining has had its ups and downs, not least due to fluctuations in the price of bitcoin and associated costs such as electricity and hardware. 

Factors affecting profitability 

1. Cost of electricity: Electricity is one of the biggest costs for miners. Some countries offer lower electricity rates, which can increase profitability. 
2. Mining hardware: The choice of hardware is crucial. ASICs (application-specific integrated circuits) are generally more efficient than graphics cards. 
3. Block rewards: As mentioned above, block rewards are halved every four years. This has a direct impact on profitability. 
4. Bitcoin value: The value of bitcoin fluctuates constantly. A high value can offset other costs and increase profitability. 

Calculating profitability  

There are several online calculators that can help you determine whether bitcoin mining will be profitable for you. These tools take into account all the factors mentioned above.

Recent developments

According to recent sources, bitcoin mining is picking up again in China despite the ban, thanks to an underground industry. This could have an impact on overall profitability by increasing competition.  

How to choose the right equipment for mining Bitcoin? 

The choice of mining hardware is a crucial step for anyone who wants to start mining bitcoin. The wrong choice of hardware can not only affect your profitability, but also lead to additional electricity and maintenance costs. 

Types of mining equipment  

1. ASIC (Application-Specific Integrated Circuit): These are devices specifically designed for bitcoin mining. They are highly efficient, but also more expensive. 
2. Graphics card (GPU): Less efficient than ASICs, graphics cards are nonetheless more versatile and can be used for other tasks. 
3. CPU: Mining via the CPU is generally not recommended due to its low efficiency.

Selection criteria 

1. Hashing power: A measure of computing power. The higher it is, the faster you can solve cryptographic problems. 
2. Electricity consumption: Energy-hungry equipment will reduce your profitability. 
3. Cost: Evaluate value for money. Cheaper but less effective equipment may not be a good deal. 

Mining software  

The choice of mining software is also important. Options such as CG MinerIn a Proof of Work system, miners contribute to determine the blockchain consensus, respecting the blockcreation protocol by being the first one to complete the current difficulty level and submitting are popular and offer good compatibility with different types of hardware.  

How Bitcoin mining works?

Mining bitcoin is a complex process that requires an in-depth understanding of the underlying mechanisms of the blockchain. It essentially involves solving cryptographic problems to validate transactions on the bitcoin network. 

The role of miners 

Miners play a crucial role in the operation of the bitcoin network. They use their computing power to solve cryptographic problems, validating transactions and creating new blocks in the blockchain. 

The mining process 

• Solving cryptographic problems: Miners solve complex mathematical problems to find a new block. 
• Transaction validation : Transactions are verified and added to the new block. 
• Rewards: For each new block created, miners receive bitcoins as a reward. 

Mining pools  

Joining a mining pool can increase your chances of winning rewards. In a pool, miners combine their computing power to solve problems more quickly. 

How is the difficulty of mining bitcoin measured?  

• Mining difficulty is a measure of the level of complexity of the cryptographic calculations that miners must perform to validate transactions and generate new blocks in the Bitcoin blockchain.  
• This difficulty is automatically adjusted by the Bitcoin network every 2,016 blocks, i.e. approximately every fortnight.  
• The aim is to maintain an average block generation time of around 10 minutes.  
• The formula for calculating difficulty is as follows: difficulty = difficulty_1_target / current_target, where difficulty_1_target represents a hashFootprint to identify initial data (sometimes unknown) by comparing it to other footprints. In cryptography, afootprint is the result of the application of an encryption software to a given message. with 32 bits set to zero.  
• The Bitcoin network checks the actual time it took to extract the last 2,016 blocks and compares it to the target of 20,160 minutes (2,016 blocks x 10 minutes). 
• Depending on this difference, the difficulty is automatically adjusted to try and get back to the target of 10 minutes per block. 
• As the number of miners and the computing power (hashrate) of the network increases, so does the difficulty of mining to maintain this rate of 10 minutes per block.  

The difficulty of mining Bitcoin is therefore a parameter that is regularly adjusted by the network to maintain a stable block generation time, depending on changes in the computing power used by miners. 

The advantages and disadvantages of bitcoin mining 

Bitcoin mining is an activity that is the subject of much debate, not least because of its environmental impact and the increasing complexity of the task. Here are some of the advantages and disadvantages of Bitcoin mining. 

Benefits 

• Bitcoin rewards: The main benefit is the Bitcoin reward that miners receive. In 2009, the reward was 50 bitcoins per mined block. This figure has been halved every 210,000 blocks, i.e. approximately every four years. 
• Transaction fees: In addition to rewards, miners also receive transaction fees, which will be their main source of income once the 21 million bitcoin limit is reached. 
• Network security: Mining contributes to the security and stability of the Bitcoin network. 

Disadvantages 

• High cost of electricity: Mining consumes a lot of electricity. Some even say that the energy consumption of the Bitcoin network is comparable to that of certain countries. 
• Increasing difficulty: The difficulty of mining increases over time, requiring more computing power. A new difficulty record was set on 12 March 2024, with a hashrate of 628 exahash per second (EH/s). 
• Environmental impact: Bitcoin mining is often criticised for its environmental impact, particularly because it uses large amounts of energy. 

Case in point: FoundyUSA and AntPool

To put these points into perspective, let’s take the example of FoundyUSA and AntPool, two mining pools that hold over 55% of the world’s Bitcoin mining power. These pools use highly specialised ASIC machines and consume huge amounts of electricity. However, they also secure a large part of the Bitcoin network. 

Why is it profitable to mine bitcoin?
