The term “mining” is inseparable from discussions about cryptocurrency.
Mining is the process of verifying transactions and adding new blocks to the Bitcoin blockchain network (Dirgantara, 2023). This process also generates new bitcoins, which are then released into circulation. Mining is performed by solving complex mathematical puzzles. It is called “mining” because, through the validation of transactions and the addition of new blocks to the blockchain, new bitcoins are created—similar to how mining gold requires effort and resources.
Likewise, Bitcoin mining requires significant computational power. To validate Bitcoin transactions, miners compete to solve cryptographic puzzles using specialized computers known as Application-Specific Integrated Circuits (ASICs). The mining process is governed by a mechanism called Proof of Work (PoW), which regulates how new transaction blocks are added to the blockchain.
Once data is recorded on the blockchain, it cannot be altered, because any change would modify the hash of that block and all subsequent blocks. A hash itself is a cryptographic output consisting of 64 hexadecimal characters, which makes the system highly secure and extremely difficult to tamper with.
Between 2020 and 2024, miners who successfully mined Bitcoin received a reward of 6.25 BTC per block. This reward is reduced approximately every four years in order to maintain Bitcoin’s scarcity and long-term value. This reduction process is known as the Bitcoin Halving.

Cryptocurrency is a form of digital currency that operates through a system known as blockchain technology. One of the most frequently discussed cryptocurrencies is Bitcoin, which was first introduced by Satoshi Nakamoto in 2008 (Lee et al., 2018). The main advantage of cryptocurrency lies in its decentralized nature. This means that transactions are not controlled by a single entity, but instead are managed by a large network of participants known as miners, who use their computing power to maintain and secure the network.

Cryptocurrency can be considered a derivative of digital currency, but it has recently become a significant and influential part of the digital financial ecosystem. Although cryptocurrencies use cryptographic technology similar to other digital currencies, they often employ different algorithmic designs.

The idea of a cryptography-based payment system was first proposed by David Chaum from the University of California, who introduced a product called DigiCash that aimed to protect the confidentiality of its users’ data. One of the major advantages of cryptocurrency is that it can be sent anywhere via the internet without the need to go through a bank, resulting in lower transaction costs (Syamsiah, 2017). However, cryptocurrencies also have several disadvantages that must be considered.
For example, cryptocurrency prices are highly volatile and do not behave like traditional currencies (Minutolo et al., 2022). Despite this limitation, many large multinational companies, such as Microsoft, PayPal, Overstock, Whole Foods, and Starbucks, have accepted Bitcoin as a payment method. Other companies, including Tesla and Square, have also taken positions in cryptocurrency. This trend indicates strong potential for mass adoption in the future.

During the COVID-19 pandemic, cryptocurrency became increasingly popular. This was partly because many people were required to stay at home, even for work-related activities. However, to meet their daily needs, people still had to find ways to earn income. In this context, cryptocurrency emerged as one possible alternative source of income during strict lockdown periods.

Minutolo et al. (2022) found that several studies indicate cryptocurrency prices react to changes in market conditions and economic fundamentals in the short term. However, cryptocurrency values tend to be more strongly influenced by economic fundamentals than by market conditions, which contributes to their high volatility. From an investment perspective, simply including Bitcoin in a portfolio can improve the overall risk–return trade-off.
Furthermore, Bezhovski et al. (2021) reported that, by transaction volume, the most widely used payment methods in e-commerce are digital wallets (41.8%), followed by bank cards (debit or credit) at 39.8%, bank transfers at 9%, and cash payments at 4.5%. These figures may vary depending on the country or region.
