Review of Literature
1) May Love Haguingan(2023)-Emotional Behaviors of Cryptocurrency Traders and
Investors. Cryptocurrency is a form of digital currency protected by cryptographic
techniques and relies on a blockchain, a secure and encrypted data structure. It was
introduced in 2008 by an individual known as Nakamoto Satoshi and gained
prominence in 2009 with the launch of Bitcoin, the oldest cryptocurrency. Other
3 | P a g e
notable cryptocurrencies include Ethereum, Tether, and Binance coins. Investing in
cryptocurrency is significant, especially during economic downturns. However, it
carries a high level of risk and often lacks comprehensive knowledge, leading to
emotional decision-making among traders and investors. This emotional aspect can be
detrimental, potentially leading to substantial losses. Trading and investing in
cryptocurrency share similarities with traditional stocks, but the key difference lies in
the significant volatility and unpredictability of the market. This paper explores the
importance of emotional control when trading cryptocurrency and how emotions can
influence price movements. Interestingly, this study reveals that using techniques like
the Wall Street Cheat Sheet to monitor emotional trading can benefit investors and
traders, particularly when combined with Technical Analysis. This information helps
newcomers to the cryptocurrency market in managing emotions to avoid substantial
losses.

artificial intelligence (AI) is undeniable, and both technologies bring novel aspects to
the market, albeit with varying degrees of complexity. In the digital money era,
4 | P a g e
blockchains facilitate secure and decentralized exchanges of personal data,
information, and logs, automating payments and enabling access to shared ledgers of
records and transactions. The combination of AI and blockchain is a widely discussed
topic, with blockchain offering a decentralized, secure, and reliable system for
automating Bitcoin payments and regulating user interactions through smart contracts,
eliminating the need for a central authority. On the other hand, AI empowers robots
with reasoning abilities and human-level intellect, creating a new dimension of
possibilities. A comprehensive assessment was conducted on the AI and blockchain
fusion from 2012 to 2022, analyzing 121 articles from the past decade that explore the
current status and rationale of this combination. The practical applications of this
integration received special attention in this critical review. Furthermore, this article
also examined the existing literature to identify gaps and challenges in the
implementation of AI and blockchain together, with a specific focus on constraints
that may arise in their combination.
4) Chen., et al (2022). Factors affecting cryptocurrency adoption in digital business
transactions: The mediating role of customer satisfaction-This empirical research
investigates the factors influencing the adoption of cryptocurrencies in Malaysia's
digital market. It is assumed that the adoption of cryptocurrencies will continue to
rise. The study focuses on several dependent variables, including social influence (SI),
transparency (TR), price value (PV), traceability (TRA), and attitude (AT), and aims
to identify customer satisfaction as a mediator variable for cryptocurrency adoption.
To ensure a comprehensive examination of the research objectives, random sampling
was employed, and 295 respondents who are cryptocurrency users in Malaysia
participated in the survey. The data obtained were analyzed using partial least squares
structural equation modeling (PLS-SEM). The results of the study indicate that social
influence (SI), price value (PV), traceability (TRA), and attitude (AT) significantly
impact cryptocurrency adoption (dependent variable) in Malaysia's digital market,
with customer satisfaction acting as a mediating factor. However, transparency (TR)
shows a negative influence on Malaysia's digital market. These findings contribute to
the limited body of literature on Bitcoin and digital currencies, providing valuable
insights for researchers seeking to understand the role of cryptocurrency and its
primary influences on the Malaysian cryptocurrency market. Moreover, future
researchers in different regions and industries can potentially replicate these findings
and utilize similar constructs to expand the existing knowledge on this topic.

5) Claire. (2019). Cryptocurrencies: The Future of Finance?-Since 2009, the circulation
of cryptocurrencies has surpassed 1600, leading to a rapid development of the
cryptocurrency market and sparking debates about their potential to challenge
traditional financial institutions. Opinions on this matter are divided, with some
commentators predicting significant disruptions to the current financial system, while
others doubt their ability to become the "future of money." Opponents of
cryptocurrencies express concerns about their association with serious crimes,
resemblance to Ponzi schemes, and the rising occurrence of crypto-scams. On the
other hand, supporters argue that cryptocurrencies offer a revolutionary payment
system, an alternative investment method, and a means of raising funds.The future of
cryptocurrencies largely depends on their legal treatment, and this is a crucial factor in
shaping their destiny. Currently, governments lack consensus on whether and how to
regulate cryptocurrencies. Some governments have imposed outright bans on specific
cryptocurrency activities, while others are taking positive steps by introducing
legislation to legitimize their use. There are also some governments that remain
undecided on whether to take any action. This research utilizes a simple SWOT
analysis to evaluate the durability and competitive positioning of cryptocurrencies.
The conclusion drawn from this analysis is that cryptocurrencies will indeed disrupt
the future of money. They are likely to become a permanent institution, but in a far
more advanced form, heavily regulated, and possibly issued by the state.
Evolution of Cryptocurrency
Conceptual Origins (1970s - 1990s): The idea of digital currency began to take shape
in the 1970s, with various early attempts to create digital cash systems. Innovators like David
Chaum explored cryptographic techniques for secure and private transactions, leading to
concepts like "eCash" and "DigiCash" in the 1990s.
Bitcoin's Emergence (2008 - 2009): In October 2008, a person or group under the
pseudonym Satoshi Nakamoto published the Bitcoin whitepaper, presenting a revolutionary
decentralized digital currency and blockchain technology. In January 2009, the Bitcoin
network came into existence with the mining of the first block, known as the "genesis block."
Early Adoption and Growth (2009 - 2013): Bitcoin's early years saw limited adoption,
primarily within tech and cryptography communities. However, it started gaining traction as a
6 | P a g e
form of digital payment and a store of value. By 2013, Bitcoin's price surged significantly,
attracting attention from the mainstream media and investors.
Rise of Altcoins (2011 - present): As the concept of cryptocurrency gained popularity,
alternative cryptocurrencies, often referred to as "altcoins," emerged. Projects like Litecoin
(2011), Namecoin (2011), and Ripple (2012) introduced variations in consensus mechanisms,
transaction speed, and use cases, expanding the cryptocurrency ecosystem.
Maturing Ecosystem (2014 - 2017): The cryptocurrency space began to mature with
the development of more user-friendly wallets and exchanges. Institutional interest in Bitcoin
grew, and blockchain technology started to gain attention from various industries beyond
finance, including supply chain management, healthcare, and real estate.
Initial Coin Offerings (ICOs) (2017 - 2018): The year 2017 saw the rise of initial coin
offerings (ICOs), a crowdfunding method where new projects issued their own tokens to raise
funds. While ICOs brought significant investment and innovation, they also became
associated with fraudulent schemes and regulatory concerns.
Cryptocurrency Mainstream Adoption (2017 - 2021): Bitcoin's price reached an all-
time high in late 2017, driving mainstream interest in cryptocurrencies. Several companies,
including notable ones like Tesla and Square, invested in Bitcoin, and various businesses
started accepting cryptocurrencies as a form of payment.
DeFi and Smart Contracts (2019 - present): Ethereum, introduced in 2015, played a
crucial role in advancing blockchain technology with its support for smart contracts. This
enabled the creation of decentralized applications (dApps) and the emergence of
decentralized finance (DeFi) platforms, providing various financial services without
intermediaries.
Central Bank Digital Currencies (CBDCs) (2020 - present): Governments and central
banks began exploring the concept of central bank digital currencies (CBDCs) as a way to
modernize their financial systems. Some countries, like China, piloted and launched their
CBDCs, marking a potential shift in the global monetary landscape.
Regulatory Challenges and Adaptations (2013 - present): Cryptocurrencies'
decentralized and borderless nature presented challenges for regulators worldwide.
Governments sought to strike a balance between fostering innovation and protecting
consumers. Regulatory frameworks for cryptocurrency exchanges, taxation, and investor
7 | P a g e
protection continue to evolve. The evolution of cryptocurrency has been marked by
technological innovations, market fluctuations, and shifts in public perception. As the
industry continues to mature, its impact on the global economy and financial systems is likely
to become more pronounced.
Blockchain Technology
Blockchain technology is a decentralized and distributed ledger system that records
transactions across a network of computers in a secure and transparent manner. Originally
developed as the underlying technology for Bitcoin, blockchain has since found applications
beyond cryptocurrencies and has been hailed as a groundbreaking innovation with the
potential to disrupt various industries. Here's an overview of blockchain technology:
Decentralization and Distributed Ledger: At its core, blockchain operates as a
decentralized database spread across a network of computers (nodes). Each node holds a copy
of the entire blockchain; no central authority controls the system. This decentralization
ensures that there is no single point of failure, making the network more resilient and less
susceptible to cyberattacks.
Blocks and Transactions: A blockchain is a chain of blocks, with each block containing a
batch of verified transactions. Transactions can represent various data, such as
cryptocurrency transfers, asset ownership records, smart contract interactions, or supply chain
events. Before being added to a block, transactions undergo verification to ensure their
validity and integrity.
Consensus Mechanisms: Different consensus mechanisms are used to achieve consensus
among the network participants about the state of the blockchain. The most common ones are
Proof of Work (PoW), used in Bitcoin, and Proof of Stake (PoS), used in Ethereum. These
mechanisms incentivize network participants (miners or validators) to reach an agreement on
the validity of transactions without relying on a central authority.
Immutability and Security: Once a block is added to the blockchain, it becomes virtually
impossible to alter the data within it. This immutability is achieved through cryptographic
hashing, where each block contains a unique code (hash) that depends on its content and the
previous block's hash. Any change to a block would alter its hash, making it inconsistent with
the subsequent blocks, thus revealing the tampering attempt.
8 | P a g e
Public and Private Blockchains: Blockchains can be categorized into public and private
(permissioned) variants. Public blockchains, like Bitcoin and Ethereum, are open to anyone
and allow anyone to participate, view, and verify transactions. Private blockchains, on the
other hand, restrict access to specific participants, often within organizations, and are used for
enterprise applications.
Smart Contracts: Smart contracts are self-executing code snippets stored on the blockchain.
They automatically execute predefined actions when specific conditions are met. Smart
contracts enable the automation and decentralization of various processes, reducing the need
for intermediaries and enhancing transparency.
Use Cases: Blockchain technology has applications in various sectors, including finance
(remittances, cross-border payments, and asset tokenization), supply chain management
(tracking and tracing products), healthcare (secure patient data management), voting systems
(transparent and tamper-resistant elections), and more. The potential use cases are continually
expanding as the technology evolves.
Challenges and Scalability: Blockchain technology faces challenges, including scalability
issues, high energy consumption (in PoW-based networks), regulatory uncertainties, and
concerns about privacy and data protection. Research and development efforts are ongoing to
address these challenges and improve the scalability and efficiency of blockchain systems.
Overall, blockchain technology has the potential to revolutionize how we exchange value and
information, providing secure, transparent, and efficient solutions in various domains. Its
impact is still unfolding, and its continued development and adoption will shape the future of
numerous industries
Block Structure: A block in a blockchain typically consists of a genesis block, a valid
block, and an orphan block
i. Block Header: The block header contains essential metadata about the block,
including its version number, timestamp (when the block was created), a unique
identifier (hash) for the previous block in the chain, and a nonce (a random number
used in the mining process). The block header is crucial for maintaining the integrity
and continuity of the blockchain.
ii. List of Transactions: The bulk of the block contains a list of validated transactions.
Each transaction represents a specific action or data entry that is recorded on the
9 | P a g e
blockchain. For example, in the case of a cryptocurrency like Bitcoin, a transaction
might involve the transfer of a certain amount of Bitcoin from one address to another.
iii. Block Hash: The block hash is a unique cryptographic identifier for the entire block.
It is generated based on the data in the block, including the block header and the list
of transactions. The block hash serves as the fingerprint of the block, ensuring its
integrity and linking it securely to the previous block in the chain.
iv. Linking Blocks: Each block in the blockchain contains the hash of the previous block
in its block header. This linking mechanism creates a chain of blocks, where each
block is cryptographically connected to the one before it. This is why it's called a
"blockchain." The linkage ensures that any change to a block's data would result in an
invalid block hash, breaking the chain and exposing tampering attempts.
v. Mining and Adding Blocks: In public blockchains that use Proof of Work (PoW) as
their consensus mechanism, miners compete to solve complex mathematical puzzles.
The first miner to find a solution gets to create a new block, including a set of
transactions they choose and broadcast it to the network. Other nodes in the network
then validate the new block and add it to their copies of the blockchain if it is valid.
vi. Block Size and Time: Blockchains have different block sizes and creation times.
Bitcoin, for example, has a block creation time of approximately 10 minutes, and its
block size is limited to 1 megabyte. Ethereum, another popular blockchain, has a
shorter block time of around 15 seconds and a dynamic block size.
vii. Block Reward: In Proof of Work-Based Blockchains like Bitcoin, the miner who
successfully creates a new block is rewarded with newly minted cryptocurrency coins
(the block reward) in addition to any transaction fees included in the block. This
incentivizes miners to participate in securing the network and adding new blocks to
the chain.
Present regulations regarding cryptocurrency
Reserve Bank of India (RBI) Circular (2018): In April 2018, the RBI issued a circular
prohibiting regulated entities (banks and financial institutions) from providing services to
individuals or businesses dealing in cryptocurrencies. This move effectively severed the
banking relationships of cryptocurrency exchanges and traders, impacting the crypto industry
in India.
10 | P a g e
Draft Bill to Ban Cryptocurrencies (2019): In mid-2019, a draft bill titled "Banning of
Cryptocurrency & Regulation of Official Digital Currency Bill" was reportedly proposed.
The draft proposed a complete ban on cryptocurrencies and proposed the development of a
central bank digital currency (CBDC) issued by the RBI.
Supreme Court Verdict (2020): In March 2020, the Indian Supreme Court overturned
the RBI circular, allowing banks to resume providing services to cryptocurrency exchanges
and users. The court ruling was seen as a positive development for the crypto industry in
India.
Reports of Potential Cryptocurrency Regulation (2021): In early 2021, there were
reports that the Indian government was considering a new bill to regulate cryptocurrencies
instead of an outright ban. The government was said to be exploring ways to classify
cryptocurrencies as an asset class and implement appropriate regulations to protect investors.
The Indian government in the 2022-2023 financial budget speech has defined
cryptocurrencies and other assets with a similar nature as ‘Virtual Digital Assets’, according
to sec 2(47A). In the 2023 budget government they have announced, as they have formed a
committee in order to check about cryptocurrency but they have not banned or disapproved
the transactions of cryptocurrency. They have imposed a 30% tax while using any form of
virtual digital assets.
Benefits of crytocurrency
11 | P a g e
Cryptocurrencies operate on decentralized networks, removing the need
for a central authority like a bank or government. This decentralization
enhances security, reduces the risk of single points of failure, and
empowers users to have direct control over their funds.
Decentralization
Cryptocurrencies use cryptographic techniques to secure transactions,
making them highly resistant to fraud and counterfeiting. Additionally,
all transactions are recorded on a public blockchain, providing
transparency and traceability
Secure and
Transparent
Transactions
Cryptocurrencies have spurred innovation in financial services, leading
to the development of decentralized finance (DeFi) platforms, smart
contracts, and new investment opportunities.
Innovation in Finance
and Technology
Cryptocurrency transactions can be executed quickly, irrespective of
geographic boundaries. This feature is particularly beneficial for
global commerce and cross-border trade.
Fast and Borderless
Transactions
Traditional financial transactions often incur high fees, especially for
cross-border transfers. Cryptocurrency transactions can significantly
reduce these costs, making them more cost-effective for remittances and
international payments.
Lower Transaction
Fees
