The process of making new bitcoins is in some ways like the process of mining for precious metals from the ground. Bitcoin mining is what people do when they want to make money
Miners spend money and time to get more crypto into circulation by solving complex problems in order to make making new coins.
Bitcoin mining is explained in this way:
A process called "Proof of Work" is used by people to compete for bitcoin rewards. They use computing power in this process (PoW). The process is called that because only miners who show that they've put in enough work (resources) have a probability of gaining the prizes.
Rewards come in two ways: (1) the "block reward," which is a new bitcoin. At the moment, the reward for each block is know to be 6.25 bitcoins. (2) the fees for all transactions in this block. End users who want to make a transaction must add a fee to the proposed transaction as a way to get miners to put it in the next block.
Why do we need to mine bitcoins?
Bitcoin mining is an important part of the system that the network uses to come to a consensus about how the LEDGER is currently set up. It is very important for people to be able to make Bitcoin transactions that are safe.
The Bitcoin network is a global public ledger that stores a huge list of time-stamped transactions. Having the ledger, which is kept by thousands of people called "nodes," lets anyone see both the current state of bitcoin ownership and the complete history of bitcoin ownership.
By design, there is no single person who decides which transactions should be added to new blocks. So instead, each node works together to figure out the state of the ledger, which is called the "truth." This is done in a similar way to how the Bitcoin protocol works. In other words, such a decentralization is what grants Bitcoin some of its most interesting features, such as censorship resistance and uncensorable aspects.
Most nodes just check that transactions are real, store the ledger, and send updates to other nodes (again, updates take the form of new blocks added to the chain). Miners, on the other hand, are a small group of nodes that compete to make new blocks. It's like when miners add new blocks to the ledger.

What is the point of mining bitcoins?
Bitcoin mining serves a lot of different purposes:
New coins are given out this way.
In the long run, it is part of a bigger system to make sure that only legitimate transactions are timestamped.
It is a way to prioritize transactions when there is a limited amount of space for them.
It gives people who work on the network (miners) money if they give up some of their own resources to keep it safe from hackers. Keep in mind that the term "attacker" mostly refers to miners. In other words, by making it hard to mine, Bitcoin makes sure that miners obey the guidelines.
Bitcoin mining is a way to keep the network safe.
Proof-of-Work mining helps to keep the Bitcoin network safe by making attackers spend more time and money on an attack than they could get from the attack itself. This makes the network more secure. Because it costs a lot of money to attack Bitcoin, it makes it very unlikely that anyone will do it, which makes it less likely that they will.
When someone wants to make money with bitcoins, they have to do something.
The new transactions are sent to all the nodes.
New transactions are put into a block by each node.
It takes each node a lot of work to find a hard proof-of-work for its block.
Proof-of-work blocks are broadcast to all nodes by a node when it discovers one
If all the transactions in the block are valid and haven't already been spent, nodes will accept the block.
Nodes show that they like a block by working on the next block in the chain, with the hash of the block that was accepted as the previous hash.
To start with, miners propose changes to the ledger. Only miners who have done the Proof of Work can add a new block. This is part of the Bitcoin protocol.
Miners can choose from a pool of possible transactions that other nodes send to the network. They can pick the ones that are valid from the pool. Such transactions are put in the "mempool." They choose transactions from the mempool based on how much money they have in them, looking for transactions with the highest fees. To make sure there is enough space for everyone, there is a fee market.
The first miner to finish the Proof of Work sends out a proposal for a new block to all the other nodes in the network. They then check to make sure that the block follows the rules of the protocol. It's important to keep in mind that all transactions in the block are valid, so there are no double spends. Also, the new block correctly references the previous block and is numbered as the next one up in the chain (ie. the new block constitutes the latest block in the longest chain). If it does, other nodes do the same thing. In this way, the new block spreads across the network until everyone agrees that it is the "truth."
Some miners even finish the Proof of Work almost at the same time and send their new block out right away. Furthermore, because of network delays and the fact that nodes are spread out across the world, they may get new proposed blocks at different times.
Keep in mind that one miner's new proposed block might be a little different from another's. This is because miners choose which transactions to put in a block, and even though they try to be profitable, location and other factors can make this a little different. It starts to spread across the network when two miners send out new blocks that are different from each other. The network chooses the chain that grows the longest at the fastest rate as the "truth" at the end.
What is the hashing algorithm for Bitcoin?
In order to keep your money safe, Bitcoin uses a military-grade encryption method called Secure Hash Algorithm 2. (SHA2). Miners get BTC when they find a random number that can only be made by running the hashing algorithm a million times. By dedicating more of their computer power to the hashing algorithm they can generate more bitcoins.
In bitcoin mining, how does the difficulty get changed?
The level of difficulty for the Proof of Work algorithm changes every 2,016 blocks, or just every two weeks. Adjustments are made to keep the time it takes to mine a new block at 10 minutes.
The difficulty adjustment takes into account how much computing power, or "hashpower," is being used to run the hashing algorithm.
Computing power makes it more difficult for everyone to mine, making it more difficult for everybody. If computing power is taken away, the difficulty of mining goes down, making it easier.
Bitcoin mining is very different from the mining of precious metals because it is very hard to change the settings. There are more miners willing to join the market if the price of gold goes up, for example. The more gold miners there are, the more gold will be made. Because of the buyers and sellers, this will eventually bring down the price of gold on the open market. In the case of Bitcoin, on the other hand, the amount of bitcoin that is made (minted) is set by the Bitcoin protocol and is not affected by the number and power of miners. This means that no matter how much mining power is put into the algorithm, the amount of Bitcoin that is made will not change.
Is it legal to mine bitcoins?
Bitcoin mining is legal in a lot of places, including the United States and Europe. People in China aren't sure about the legality of bitcoin mining right now.
Bitcoin mining: Is it profitable?
Bitcoin mining is a very competitive business with very small profit margins. Electricity is the main source of energy, but there are also a lot of upfront costs for hardware and places to store the hardware. The main piece of hardware is called an Application Specific Integrated Circuit (ASIC), which is a computer that only runs the Bitcoin hashing algorithm. Profitability is mostly dependent on having access to cheap electricity that can be used to run the most productive ASIC devices.
Bitcoin mining is a naturally stable system. As the value of bitcoin rises, miner margins get bigger. This makes more miners want to join the market. However, new people make it more difficult to make new blocks. This means that everyone will have to spend more money, which means that profits will be lower for everyone. Bitcoin miners have historically quit when the price of the currency drops for a long time because the costs of mining outweigh the profits.
In what ways does bitcoin mining impact how much bitcoin costs to buy and sell?
Most of the time, miners sell their bitcoins to pay for the costs of mining. So, these costs add to the pressure to sell at a low price. Miners may try to make more money by holding or selling Bitcoin based on how the market is moving. This could make Bitcoin's price more or less volatile. There is a claim here that when the price of Bitcoin is going up, miners might try to hold on longer in the hope that they can make more money. This would mean that there would be less pressure to sell, which would lead to a faster price rise. When the price of Bitcoin goes down, however, miners are more likely to sell not only their assets, but also any new bitcoin they've made. This, in essence, would make the market more volatile on the downside.
