What is Bitcoin (BTC)?
Bitcoin is a decentralized, digital currency on the blockchain that is secured by cryptography and is not controlled by a government or financial institution. It can be used as a means of payment for goods or services or as a digital store of value.
Bitcoin was first introduced in 2009 in a white paper published by Satoshi Nakamoto. No one knows who Satoshi Nakamoto is and no one can say whether it is an individual person or a group. The paper described a new electronic money system that was based on a decentralized computer network and not on a central authority. After its launch, Bitcoin gained a small but interested following. With the years and progress of Bitcoin technology and infrastructure, Bitcoin has also become interesting for the general public. Bitcoin is often referred to as “digital gold” because, like gold, there is a limited quantity and serves as a store of value. In 2013, the US Department of Justice issued guidelines that stated that virtual currencies such as Bitcoin are legal and can be regulated as a form of money. This helped legitimize Bitcoin and led to a surge in its value. However, it remains a very mobile currency whose value can fluctuate significantly.
Why is Bitcoin mining needed?
Since cryptocurrencies on a blockchain, such as Bitcoin, are not centrally regulated or monitored, Bitcoin miners are fundamentally important because they confirm and verify transactions by solving complex mathematical crypto calculations, which are finally included in a block in the blockchain. If no one were to validate transactions made, fraudsters could issue bitcoins and other cryptocurrencies multiple times due to the decentralized nature of the blockchain. Mining prevents fraud and strengthens users' trust in the cryptocurrency.
What is mining — mining bitcoins?
The name mining means “mining” in German. But mining does not mine or create new coins such as Bitcoin. Technically speaking, mining is a process that ensures that the continued existence of the system is ensured by creating new transaction blocks. Mining is not primarily used to mine new coins, but is specifically about verifying, creating and adding new transaction blocks to the blockchain. In the course of this, however, new bitcoins are also brought into circulation — as a reward for the entire process.
There are therefore two objectives:
1. the validation of transactions with cryptocurrencies on their blockchain
2. as well as generating new cryptocurrency such as Bitcoin.
The process called “mining” ensures that blocks are added to a chain in a blockchain. Each block contains a list of transactions and a “hash.” A hash is a unique code that is generated from the content of the block. The hash of each block is linked to the hash of the previous block in the chain, creating a secure and uninterrupted connection between all blocks in the chain.
What do miners do?
Mining is a comprehensive process involving many miners who perform a wide range of hash functions with different nonce values. In addition to transactions and the hash, each block contains a “nonce.” “Nonce” means something like “number that is only used once.” It is the number that must be found out by a miner before it can resolve a block in a blockchain.
When a block of transactions is generated, miners run it through a process. By applying a mathematical formula, the transaction and its information are converted into something much shorter. This abbreviation is actually just a string of letters and numbers and is called a hash. The miner must find a nonce number which, together with the data in the block, results in a hash that starts with the correct number. The must must enter various numbers in the Nonce field and calculate the associated hash until it finds a number that meets the specification.
What is important is the fact that no one can calculate a nonce. Simply trying things out is therefore also a luck factor. This makes it possible for anyone to improve their chances of finding a block in which they increase their hash rate. When mining was successful and the validation of a new block has taken place, the search for a blockchain nonce starts again.
What do you need to mine bitcoins?
In the past, Bitcoin mining could be carried out on the CPUs of individual computers. Mining with a normal computer results in a hash rate of approximately 1 to 3 million per second. However, there is now so much computing power in the Bitcoin network that mining is only worthwhile using special mining hardware. Bitcoin miners are called ASIC miners, which have very high computing power and more efficient power consumption to perform more hashes with less power consumption.
As a prospective miner, you therefore need the following:
- Mining hardware (e.g. Bitmain Antminer S19 Pro, Antminer S19 XP)
- electricity
- Mining software (Nice Hash, Hive OS,...)
- Mining pool (Ethermine,...)

The Bitcoin Lightning Network
The Bitcoin Lightning Network is an extension of blockchain technology developed for the Bitcoin protocol to improve the scalability and speed of Bitcoin transactions. The Lightning Network is designed to increase the number of transactions recorded in a block and reduce the time it takes to process transactions.
The Lightning Network works by allowing transactions to take place outside the main blockchain. Instead, transactions are processed in so-called “channels,” which are opened between two users. When a user wants to send a transaction to another user, it is not recorded directly on the main blockchain, but in the channel that the two users have shared. This allows users to execute multiple transactions without having to record every single transaction on the main blockchain.
The Lightning Network has the potential to significantly improve the scalability and speed of Bitcoin transactions. It could help solve the problem of the limited number of transactions per block on the main blockchain and reduce transaction processing time. However, there are also concerns about security and the potential impact of the Lightning Network on the main blockchain. It is important that users carefully consider the risks and opportunities of the Lightning Network before using it.
The future of Bitcoin
The future of Bitcoin is difficult to predict. Some experts believe it has the potential to revolutionize the financial industry and become a widely accepted currency. Others are more skeptical and believe that it is a speculative bubble that is doomed to failure. What is certain is that Bitcoin has come a long way. It has gained a considerable following and is accepted by a number of dealers, companies and now also a few states. Whether it will continue to grow in the future remains to be seen, but it is definitely a technology and currency worth paying attention to.
There are many factors that could influence the future of Bitcoin. One important factor is regulation by governments and central banks. Some countries have already regulated Bitcoin and recognized it as a legitimate means of payment, while other countries are banning or restricting it. Another important question is whether Bitcoin will be accepted by mainstream users and institutions in the future. If the use of Bitcoin as a means of payment becomes more widespread and is accepted by more people and companies, this could lead to further adoption and a higher price.
In conclusion, the future of Bitcoin is uncertain and depends on many factors. It is possible for Bitcoin to establish itself as an established and widely used means of payment, but there are also risks and uncertainties that need to be considered. However, the Bitcoin adaptation is currently looking very good and we are very optimistic about the future.
