Is Bitcoin Mining Feasible?

Bitcoin mining started pretty well and those who practiced it earned handsome amounts. They even earned up to 50 BTC. There was no requirement for them to carry out the mining in specific offices. Rather they started mining from the comfort of their homes.

You would have around $500 worth of bitcoin in your wallet in 2020 if you had only been successful in mining one Bitcoin block since 2010. Before determining if it's even conceivable for you to benefit from bitcoin mining, there are a few fundamentals to understand if you're eager to study and want to generate an income.

All proof-of-work blockchains are built on the foundation of mining, which is characterized by the key ideas outlined below.

Bitcoin Block Prize

6.25 bitcoins are awarded to miners. The halving in 2024 will result in a drop to this amount to 3.125 bitcoins. The first miner to complete the riddle receives the prize (plus transaction costs).

Every mining machine on the network goes through this procedure once every ten minutes. The puzzle's network complexity is updated every 2016 blocks (or around 14 days) to make it such that, on average, one computer can finish it in 10 minutes.

What is Mining Hardware?

Computers designed specifically for mining bitcoins are known as mining hardware. Everything is dependent on how capable and powerful your hardware is. If it's more powerful, it will help you mine more bitcoins and generate revenue.

What’s a Hashrate?

The processing power of a miner is gauged by its git hashrate.

In simple words, the more miners mining bitcoin in the hopes of receiving a reward, the more challenging the problem is to solve. The ability to mine more bitcoin will depend on who has the highest processing power (hashrate). A miner is more likely to find answers if the machine's computing power is strong.

Hashrate was first quantified in hash per second (H/s) in 2009. As mining grew over a while, H/s quickly became often prefixed with the following SI units:

Kilohash:  KH/s (thousands of Hashes/second)

Megahash: MH/s (millions of Hashes/second)

Gigahash: GH/s (billions of Hashes/second)

Terahash: TH/s (trillions of Hashes/second)

Petahash: PH/s (quadrillions of Hashes/second)

How do Bitcoin miners figure out their salary?

You've probably heard the alarming tales about how much electricity Bitcoin mining uses. It is a truth that miners pay the cost of energy consumption for the mining. To be viable, mining must provide more income than these expenses along with the initial investment in mining equipment.

Mining Income

Depending on the price of bitcoin, one Bitcoin mining device (ASIC), such as the Whatsminer M20S, earns about $12 in daily income in February 2022. The money from mining Bitcoin is twice as much as mining with the same number of GPUs you could purchase for one ASIC, as compared to other cryptocurrencies like Ethereum, which are mined with graphics cards. A Whatsminer M20s costs about the same as thirteen AMD RX graphics cards.

The block reward and the fees that bitcoin users pay the miners for safely logging their transactions into the blockchain are how bitcoin miners make money.

What does Block Reward mean?

The owner of the mining device that finds the new block the fastest receives a certain amount of freshly created bitcoin every 10 minutes or such.

In 2009, Satoshi Nakamoto initially fixed the mining reward at 50 BTC and encoded all future drops to the prize.

Every four years, the Bitcoin algorithm is programmed to reduce this reward by half. Late in 2012, it decreased to 25 BTC, then in the middle of 2016, it was again cut in half to 12.5 BTC.

What's a Transaction Fee?

The transaction fees that Bitcoin users must pay when sending and receiving BTC are the second source of income for Bitcoin miners.

Every transaction is documented on a blockchain that cannot be altered and is duplicated on every mining device.

The miners themselves are responsible for maintaining the records in Bitcoin instead of a central bank, and they also retain a portion of the transaction fees.

How to Gain Profit from Bitcoin Mining?

Starting off, there are several factors in Bitcoin mining. Due to this, purchasing bitcoin on an exchange may be a more convenient way to turn a profit. However, mining bitcoin can be more profitable when done well than merely purchasing and "hodling". Hodling means when you refrain from selling the bitcoin.

The price of Bitcoin itself is one of the key factors for miners. You will need to generate enough bitcoin from mine to meet your recurring expenses and recoup your initial investment in the equipment.

1. Electricity Expense

Electricity prices differ from one nation to another. A cheaper price for industrial power is also charged in several nations to promote economic expansion. As a result, the cost of power for a mining farm in Russia will be half that of a mining farm in the United States.

Practically speaking. If you live in a country like China, Russia, or Kazakhstan, where power costs $0.045 per kWh, running a Whatsminer M20S for a month would cost you about $110. 

1. Hardware System

The cost of hardware varies considerably across manufacturers and mostly relies on how little energy is consumed by the device relative to the amount of computational power it generates. You'll mine more bitcoin if you have the higher processing power. Your monthly expenditures will be reduced due to less energy consumption.

Miners should consider the equipment's profitability and lifespan before investing money. It frequently makes sense to favor "price per TH" above "watts per TH" if the hosting cost is low enough since reduced operating expenditures (OpEx) will compensate for the loss in machine efficiency, and vice versa if hosting costs are high.

1. Credible Mining Pool

Nowadays, every miner must use a mining pool to mine. The network of Bitcoin mining equipment is so big that your odds of consistently discovering a block (and collecting the block reward and transaction fees) are incredibly slim, whether you're mining with one machine or a thousand.

Slush Pool and F2 Pool are the two oldest pools. One of the biggest Bitcoin mining pools, F2Pool contributes to about 15% of the whole Bitcoin network.

PPS+ is the payment system used by F2Pool. Because PPS+ pools pay transaction fees and block rewards to miners independent of whether the pool itself successfully mines each block, they remove the risk from the miners. PPS+ pools typically pay the miners after each day.

1. The fee for Selling Bitcoin

You might need to sell your coins on an exchange like Rain if you are a part-time miner. It relies on the pricing structure of the exchange and the current condition of the orderbook whether your fees are large or low at any given time.

However, if you work as a professional miner like F2 or Bitmain, you probably have highly beneficial agreements with OTC desks to sell your coins for little to no cost, depending on the market situation. For their coins, some miners are even paid more than the current price. In either case, because professional mining operations work with Bitcoin on a massive scale, they have greater negotiating power.

Is it possible to mine directly to an exchange?

You still need to think about where to keep the bitcoin you mine even if you have invested the time to learn about mining and have located a place with affordable electricity for your devices.

Although it is possible to mine directly from a pool to exchange, we advise keeping your bitcoins in a wallet that gives you access to the private keys.

Does CPU mining yield profit?

No. CPU mining has never been lucrative unless you were among the first users to mine Bitcoin. Again, nowadays, you need an ASIC and an agreement with a power supply enterprise to make any money mining Bitcoin. 

Conclusion

It’s highly unlikely for individual miners to earn money at their homes. You have to invest a lot in hardware resources and electricity. 

However, the future is bright and the situation will improve when advancements in ASIC mining hardware reach a threshold of diminishing returns. Combining this with accessible, affordable, and sustainable electricity options for consumers may enable small-scale, independent miners all over the world to once again profit from their mining operations.
