1. Introduction

Cryptocurrencies (such as Bitcoin, Ethereum, Tether, Dogecoin, and other digital assets) represent a part of disruptive technology-driven innovations in the global banking system (Katz & Lindell, 2022). Cryptocurrencies, built on blockchain technology, have huge potential to transform business-to-business (B2B) and business-to-customer (B2C) transactions if they are adopted widely, due to their ability to reduce transaction costs, enhance transparency, and enable faster, secure cross-border payments (Stallings, 2023). The decentralized nature of cryptocurrencies also eliminates the need for intermediaries, streamlining transaction processes for both businesses and customers in various industries (Menezes et al, 2022). Cryptographic principles (i.e., the fundamental ideas and methods applied to secure communication and data) hinge on concepts like integrity, confidentiality, authentication, and non-repudiation that support encryption and hashing techniques, making transactions immutable and reducing risk of fraud (Paar & Pelzl, 2023; Schneier, 2024). The capacity of cryptocurrencies to transform economies by providing new investment opportunities, particularly in developing countries like Nigeria, where financial services from traditional banks are limited, unreliable, and slower, indicates digital currencies have huge potential to disrupt the global banking system (Adewale, 2024; James & Obianuju, 2024; Kowalski, 2023; Olorunfemi & Adebayo, 2023).

While digital currencies are disrupting traditional banking systems and gaining more popularity worldwide, Nigeria, a country facing financial challenges such as inflation, currency devaluation, and a large unbanked population, has not recognized cryptocurrencies as a national currency (Chukwu, 2024; Oyelami & Bello, 2023; Williams, 2022; Smith et al, 2023). Regulatory concerns, risk of financial instability, fear over illicit activities, challenge to the adoption of e-Naira, and the expected negative impact on monetary policy control are reasons the Nigerian government has not recognized cryptocurrencies as a national legal tender (Obi & Adefolaju, 2022; Adewale, 2024; Attah, 2022; Emeka & Omotola, 2023; Abubakar, 2022). Nigeria therefore presents an interesting case for understanding how cryptocurrencies can provide alternative financial solutions and reshape the economy (Kowalski, 2023).

This research proposal aims to examine the disruptive nature of cryptocurrencies (as distinguished digital currencies without legislated or intrinsic value). It will also access the potential impact of cryptocurrencies on Nigeria’s traditional banking systems and evaluate how they can transform the dwindling economy by enhancing financial inclusion and economic development (Oyelami & Bello, 2023; Emeka & Omotola, 2023).

2. Which cryptocurrencies are adopted in Nigeria and what is their impact on Nigeria’s economy?

Cryptocurrencies (e.g., Bitcoin, Ether, Litecoin, USDT, and BNB) have gained traction in Nigeria despite the federal government not recognizing them as legal tenders. Here are the economic benefits of the most common cryptocurrencies in Nigeria:

a. Bitcoin (BTC): Bitcoin, the most popular cryptocurrency in Nigeria, holds a significant share of cryptocurrency transactions. According to Abubakar (2022) and Emeka and Omotola (2023), Nigeria ranks consistently among countries with the highest Bitcoin trading volume, due to remittances, savings, and investments necessitated by inflation and currency devaluation.

Impact on the Economy:

• Bitcoin provides a less cumbersome alternative to expensive and slow traditional remittance channels (e.g., Western Union). Nigerians, especially those in the diaspora, are using Bitcoin for international transaction and cross-border payments, which are not only faster, but cheaper than bank wire transfers (Adewale, 2024; Attah, 2022).
• Uncertainty surrounds the Naira since President Bola Ahmed Tinubu’s administration, particularly after the Central Bank of Nigeria (CBN) introduced a “floating exchange rate system,” which has peaked inflation and devalued the currency, Nigerians are turning to Bitcoin as a reliable store of value and a hedge against the declining purchasing power of local currency (Chukwu, 2023).
• Bitcoin provides new investment avenues for Nigerians. Investors, professionals, students, and traders of various ages are engaging in Bitcoin trading for speculative purposes, hoping to gain from its volatility (Christensen, 1997).

b. Ethereum (ETH): Ethereum is the second most popular cryptocurrency in Nigeria due to its decentralized application platform, which supports smart contracts and decentralized finance (DeFi). Tech-savvy Nigerians are exploring opportunities in blockchain development, decentralized applications (Dapps), and tokenization (James & Obiajulu, 2024).

Impact on the Economy:

• Ethereum’s platform is driving innovation in various industries, and particularly within Nigeria’s growing tech and startup ecosystem as well as in fintech and DeFi. Nigerian software developers are also exploring Ethereum’s blockchain to create financial solutions for the unbanked population (Obi & Adefolaju, 2022).
• Ethereum is pioneering DeFi by offering decentralized financial services (such as lending, borrowing, and staking without intermediaries), a disruptive effort that promotes financial inclusion by providing access to financial services outside traditional banking (Olorunfemi & Adebayo, 2023; Oyelami & Bello, 2023; Paar & Pelzl, 2023).

c. Litecoin (LTC): Litecoin (also known as the “silver to Bitcoin’s gold”) is another commonly used cryptocurrency in Nigeria due to its faster transaction times and lower fees when compared to Bitcoin.

Impact on the Economy:

• Litecoin is used for daily transactions and peer-to-peer (P2P) payments, particularly due to lower transaction costs, which make it preferrable for micropayments—and online businesses.
• As an alternative to traditional remittance methods, like Bitcoin, Litecoin is helping Nigerians to avoid high transaction fees for cross-border transaction and online payments.

d. USDT (Tether): USDT, also known as Tether, is a stablecoin pegged to the US dollar. It is widely used in Nigeria to safeguard volatility inherent in other cryptocurrencies. It provides a stable value for people looking to store their wealth in digital form without risking rapid price fluctuations in global markets (Paar & Pelzl, 2023).

Impact on the Economy:

• USDT offers an alternative to store value in a more stable asset against the volatile naira, thus, Nigerian cryptocurrency traders often convert their holdings into USDT to preserve value during market downturns (Olorunfemi & Adebayo, 2023; Oyelami & Bello, 2023).
• USDT enhances trade efficiency in cross-border transactions where individuals and organizations want a stable, reliable currency without fluctuations in value (Obi & Adefolaju, 2022).

e. BNB (Binance Coin): This native cryptocurrency of the Binance exchange is commonly used in Nigeria, where BNB offers users various financial services, including staking, saving, and trading, making it a popular choice.

Impact on the Economy:

• Binance offers a key cryptocurrency trading platform with lower transaction fees, a reason for its widespread adoption in trading activities (Johnson & Walker, 2023; Katz & Lindell, 2022).
• The integration of BNB into various DeFi projects allows Nigerians to earn passive income through staking and yield farming (Smith et al, 2023; Stallings, 2023).

3. Research Aim and Objectives

Aim:
The aim of this proposed study is to analyse the impact of cryptocurrencies on traditional banking systems in Nigeria, with focus on how the adoption of digital currencies can transform the Nigerian economy.

Objectives:

• To explore the extent to which Nigeria has adopted cryptocurrencies and their influence on the financial sector (James & Obiajulu, 2024).
• To analyse the disruptive impact of cryptocurrencies on traditional banking services such as payments, loans, savings, and currency exchange (Williams, 2022; Smith et al., 2023).
• To access the regulatory challenges faced by cryptocurrencies in Nigeria and their implications for the banking sector (Chukwu, 2023; Obi & Adefolaju, 2022).
• To examine the potential of cryptocurrencies in fostering financial inclusion and economic development in Nigeria (Olorunfemi & Adebayo, 2023; Attah, 2022).
• To recommend effective ways the Nigerian banking sector can adapt to the growing presence of cryptocurrencies (Kowalski, 2023; Emeka & Omotola, 2023).

4. Literature Review

The literature review will examine existing research on the rise of cryptocurrencies globally, with focus on Nigeria, where adoption of cryptocurrencies remains slow despite huge benefits from the disruptive innovations which are evident in other countries (e.g., El Salvador, Central African Republic, Ukraine, Panama, and Brazil). Key areas of the literature review include:

• Cryptocurrency Adoption: Studies indicate the adoption of cryptocurrencies is rapidly increasing in developing countries, including Nigeria, due to the demand for alternatives to traditional banking (James & Obiajulu, 2024; Smith et al., 2023).
• Disruptive Innovation Theory: Christensen’s theory on disruptive innovation explains how technology-driven disruptive innovations in fintech and other new technologies are transforming the global markets. The theory will be applied to analyse the role of cryptocurrencies in disrupting traditional banking systems (Christensen, 1997; Johnson & Walker, 2023).
• Traditional Banking versus Cryptocurrencies: This study will explore relevant research on the differences between financial services offered by traditional banks and how cryptocurrencies provide decentralized alternatives (Williams, 2022; Abubakar, 2022).
• Regulation of Cryptocurrencies: The study will examine Nigeria’s complex regulatory landscape for cryptocurrencies, with focus on CBN and existing literature on financial management, corporate governance, and monetary policy control to provide insights into the current and future policies capable of facilitating adoption and legalization of digital assets in the country (Chukwu, 2023; Obi & Adefolaju, 2022).

5. Methodology                  

This research will adopt a mixed-methods approach (that is, a combination of quantitative and qualitative techniques). The researcher will distribute surveys to banking professionals, cryptocurrency users, and the public to collect primary data on perceptions of cryptocurrencies and their impact on traditional banking systems (James & Obiajulu, 2024; Smith et al., 2023). The researcher will also conduct interviews with key stakeholders (such as bank executives, fintech leaders, and regulators) to gain insights into the potential transformation of the Nigerian economy through cryptocurrency adoption (Adewale, 2024; Attah, 2022).

Data Collection:

• Primary data collection process for the research will involve online surveys as well as interviews conducted via Zoom or in person.
• Secondary data sources will include Central Bank of Nigeria (CBN) reports, financial statements, and blockchain data.

6. Expected Outcomes

This academic research will identify key areas where cryptocurrencies are disrupting traditional banking services and explore their potential to promote financial inclusion in Nigeria. Results from the analysis will also provide useful recommendations for Nigerian banks and policymakers on better ways to integrate cryptocurrencies into the financial ecosystem (Adewale, 2024; Attah, 2022).

7. Significance of the Study

Findings from this research will be useful to stakeholders in Nigeria’s financial system. For banks and other financial institutions, an understanding the disruptive nature of cryptocurrencies to be discussed in this proposed research is essential for technology adoption planning whereas regulators in the financial sector will find results from this research foundational for developing policies that encourage innovation, and at the same time, safeguard Nigeria’s financial system. For the public, this research will explain ways that cryptocurrencies can enhance access to financial services (Kowalski, 2023; Emeka & Omotola, 2023).

10. Conclusion

Nigeria became the first African country and second in the world to introduce a government-backed digital currency in 2021. During the launch of the e-Naira, the CBN Governor, Mr. Godwin Ifeanyi Emefiele (CFR), said the currency had drawn “overwhelming interest and encouraging response,” emphasizing its potential to improve the security of digital transactions, boost financial inclusion,, and enhance local and cross-border trade, among other benefits. The e-Naira, however, failed to achieve these goals. This MBA research provides a detailed analysis of how cryptocurrencies are disrupting traditional banking systems in Nigeria as well as assess cryptocurrencies’ potential for economic transformation despite federal government’s aversion to the digital currencies—except e-Naira, which has failed to compete favourably with cryptos. Therefore, understanding the implications of cryptocurrencies for banking is crucial for the future of Nigeria’s financial sector (Christensen, 1997; Adewale, 2024; Abubakar, 2022).
