Cryptocurrencies are virtual or digital currencies that use cryptography (a form of secret code to communicate certain information/data) to secure and verify transactions whilst prohibiting the production of new units. Bitcoin is the most popular and well-known cryptocurrency, however, there are dozens of others available in marketplaces throughout the world, each with distinctive features and traits. Litecoin, Ethereum, Ripple, and Bitcoin Cash are a further few well-known cryptocurrencies. Among the many uses for cryptocurrencies are as a store of value, a medium of exchange for goods and services, and speculative investments. Cryptocurrencies’ value is quite volatile and can change quickly depending on market demand and other variables due to the fact that they are not backed by any tangible assets or governments.

Mining cryptocurrency is essential to ensure that there is an adequate supply of certain currencies to sustain a market. Cryptocurrency mining requires employing strong computers and specialised technology to solve difficult mathematical problems, which uses a lot of energy. Because of the negative effects mining has on the environment, such as increased carbon emissions and climate change, the high energy consumption linked with mining is a major source of worry. Additionally, mining may result in higher local energy costs and a possible concentration of mining power in the hands of a small number of very powerful organisations, raising questions about the security and decentralisation of the network. Concerns regarding the viability and security of cryptocurrencies are raised by these effects on the environment, energy costs, and network centralization.

Another benefit of cryptocurrencies is transparency. Transactions using cryptocurrencies are often recorded on a public ledger, making them transparent and auditable. This can help to reduce fraud and corruption, as all transactions are visible to anyone on the network. This transparency also enhances the security of the system, making it more difficult for bad actors to engage in illegal activities like money laundering or terrorism financing.

Security is another key benefit of cryptocurrencies. Cryptocurrencies use strong encryption techniques to secure transactions and prevent fraud. The decentralized nature of cryptocurrencies also makes them less susceptible to hacking and cyberattacks, as there is no central point of control that can be targeted by attackers. Additionally, those without access to traditional banking institutions may be able to receive financial services through cryptocurrencies. This includes those who reside in remote regions, don’t have a government-issued ID, or are unable to pay the costs related to regular banking. Without the requirement for a physical bank, cryptocurrencies may offer financial services to these people, creating new potential for financial inclusion and empowerment.

Extreme price volatility has been observed in cryptocurrencies, with prices swinging significantly in a short amount of time. Because it may be challenging to create an appropriate budget and because they might result in substantial financial losses, they may be a dangerous investment for both people and organisations. Due to the absence of a central government or body to regulate prices or offer monitoring, the unregulated nature of the cryptocurrency market has the potential to make this volatility worse. Further, given that cryptocurrencies’ value is mostly driven by supply and demand, their limited use as a form of payment may potentially contribute to price volatility.

The absence of control and regulation for cryptocurrency is another possible problem. They may be susceptible to illicit acts like money laundering and financing terrorism since they are not governed by governments or central authorities. Because of this, criminal groups may view them as a desirable target and utilise cryptocurrencies to avoid capture and launder money. The irreversible nature of bitcoin transactions can sometimes be a drawback since it prevents transactions from being undone after they have been completed. As the cash cannot be reclaimed, this might be troublesome if an error is made or a fraudulent transaction takes place.
