Bitcoin Mining
With extensive experience as an electrical/software/coding engineer along with having a diverse financial background, Thomas Wettermann’s areas of interest include Machine Learning (ML), artificial intelligence (AI), and Financial Technology (FinTech). For the past few years, Thomas Wettermann has focused on the underlying technologies that support and promote all phases of cryptocurrency, Web 3.0, and metaverse ecosystems.

What is Bitcoin Mining?
Bitcoin uses a consensus mechanism known as Proof-of-Work (“PoW”) to add new blocks onto the blockchain. The application of the PoW consensus mechanism will verify all Bitcoin transactions before they are added to the blockchain. Bitcoin “miners” compete with one another to verify each transaction and then add the next verified block onto the blockchain.
Generally, cryptocurrency mining refers to the process of earning cryptocurrencies by solving cryptographic equations by employing highly efficient and ultra-fast computer systems. For Bitcoin, this process involves verifying data blocks wherein each 250MB data block may include from about 1,500 to about 4,000 Bitcoin transactions.
Aside from this block verification process, cryptocurrency mining involves the process of adding transaction records (in the form of a block) to a public record or public ledger. This public ledger is known as the blockchain. Complex encryption techniques are then used to secure this transaction data. This is where the term “cryptocurrency” came from.
On January 3, 2009, the first Bitcoin was mined by its alleged founder Satoshi Nakamoto. At the time of its launch, Bitcoin could be mined by way of central processing units (CPUs) using ordinary laptops or desktop computers. Essentially, CPUs control how computer code is processed and executed.
In these early Bitcoin days, there was not a lot of miner competition. Therefore, the processing power required to create new blocks and earn mining rewards could be processed on ordinary CPU devices, like desktop and laptop computers.
However, as the price of Bitcoin began to escalate and Bitcoin’s popularity grew, global mining activities and mining competition increased. This increased competition brought more hashing computer power online to compete for solving these equations. Hash power is the power that a computer must expend to run and solve different hashing algorithms.
As Bitcoin mining continued to attract competition, mining difficulty increased, requiring more and more hash power. To gain a competitive advantage, Bitcoin miners began implementing graphic processing units (GPUs) to harness more hashing computer power.
Unlike the predecessor CPU devices, GPUs perform a very specific range of computational tasks. GPUs were originally designed for gaming applications since they excel at computing mathematical operations in parallel. These devices can also be programmed to compute other mathematical operations such as the ones required to mine Bitcoin.
Miners used GPU devices for many years before the launch of more superior mining hardware in the form of ASICs (Application Specific Integrated Circuits). As block difficulty continued to increase, hardcore Bitcoin miners started mining with ASIC-based machines. These ASIC-based machines are often installed in thermally-regulated data centers or mining farms. This technology was developed solely for mining with hash rates significantly higher than GPUs.
The successful miner must first verify a block of transactions and then solve complex mathematical problems. The first miner to solve the mathematical problem earned financial rewards in the form of newly minted or “mined” Bitcoin. Miner competition is intense as there can only be one successful miner for each verified block.

Trading digital financial assets such as cryptocurrencies can carry a high level of risk, and may not be suitable for all investors. Before deciding to invest, purchase, and/or trade cryptocurrency you should carefully consider your investment objectives, level of experience, adversity to risk, and volatilities. The possibility exists that you may sustain a loss of some or all of your initial investment; therefore, you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with cryptocurrency trading, and seek advice from a qualified and independent financial advisor.
