3. Introduction of
Cryptocurrency
 Cryptocurrency is a type of digital currency that is secured and verified using advanced
encryption techniques and operates on a decentralized network.
 A medium of exchange like normal currencies
 Designed for the purpose of exchanging digital information
 Exchanging process made possible by certain principles of Cryptography
 It is not controlled by any central authority, such as a government or bank, and uses a
distributed ledger technology called a blockchain to keep track of transactions and maintain
trust
 Cryptocurrency is a digital asset designed to work as a medium of exchange, using strong cryptography to
secure financial transactions and control the creation of additional units of the currency.

4. History Of
Cryptocurrency
• The history of cryptocurrency can be traced back to the late 1990s, when various attempts were made to
create digital currencies, such as B-money and Bit Gold. However, these early attempts did not gain
widespread adoption or success.
• The modern era of cryptocurrency began in 2009, with the creation of Bitcoin by an unknown person or
group name Satoshi Nakamoto. Bitcoin was the first decentralized digital currency to use a peer-to-peer
network to verify and record transactions on a public ledger called a blockchain. The creation of Bitcoin
was motivated by the desire to create a currency that was not subject to the control of governments or
banks, and could be used for secure and private transactions online.
• After Bitcoin's launch, several other cryptocurrencies were created, including Litecoin, Namecoin, and
Ripple. Each of these cryptocurrencies was designed to address specific limitations of Bitcoin, such as
slow transaction times or limited functionality.
• Bitcoin In July 2010, bitcoin began trading at US$0.0008 (0.066 INR) and current price is US$23,932.10
(1976814.20 INR)

5. Crypto and
Blockchain Technology
• Blockchain technology is an advanced database mechanism that allows
transparent information sharing within a business network. A blockchain
database stores data in blocks that are linked together in a chain
• Cryptocurrencies are digital assets that use blockchain technology to
enable secure and decentralized transactions.
• A blockchain is a decentralized, secure, and transparent ledger that records
all transactions in a chronological chain of blocks.
• Blockchain technology provides the infrastructure for cryptocurrencies to
operate without intermediaries, such as banks or payment processors,
which can lead to faster and cheaper transactions.
• The transparency and immutability of the blockchain provide a high level
of security, preventing fraud and ensuring the integrity of the network.
• Cryptocurrencies are built on blockchain technology, with each transaction
recorded on the blockchain and verified by multiple nodes in the network.
• Overall, the relationship between cryptocurrency and blockchain is
fundamental, with blockchain technology serving as the underlying
infrastructure that enables secure, decentralized transactions of digital
assets like cryptocurrency.

7. Fiat Currency vs Cryptocurrency
Fiat Currency Cryptocurrency
• Physical in nature (banknotes and
coins).
• Digital or virtual in nature.
• Issued and regulated by a central
authority (government or central
bank).
• Decentralized, meaning not
regulated or issued by a central
authority.
• Unlimited Supply government can
produce as needed
• Limited Supply each cryptocurrency
has a set maximum
• Value determined by market and
regulation
• Value determined by supply and
demand
• Issued by Government • Produce by Computers
• Subject to various types of tax such
as succession tax , gift tax , income
tax
• Has anonymity and not affected by
taxes

8. • Cryptocurrency mining is the process of verifying transactions on a blockchain network and adding them to the public ledger,
known as the blockchain. Miners are rewarded with newly minted cryptocurrency tokens for their work in maintaining the
network.
• Mining Equipment: Cryptocurrency mining requires specialized hardware such as ASICs (Application-Specific Integrated Circuits) or
GPUs (Graphics Processing Units), which can be expensive to purchase and operate.
• Mining Pools: As mining becomes more competitive, miners can join mining pools to increase their chances of earning rewards. In
a mining pool, several miners combine their computing power to solve the cryptographic puzzles and share the rewards.
• Energy Consumption: Cryptocurrency mining can be energy-intensive, as the mining equipment requires significant amounts of
electricity to operate. This has led to concerns about the environmental impact of mining, particularly for cryptocurrencies that
use the PoW consensus algorithm.
• Proof-of-Work: Most cryptocurrencies use a consensus algorithm known as Proof-of-Work (PoW), which requires miners to solve
complex mathematical puzzles using powerful computers to verify transactions and earn rewards.
• Profitability: Cryptocurrency mining can be profitable, but it is highly dependent on factors such as the price of the token, the cost
of electricity, and the difficulty of mining. As the mining industry becomes more competitive, profitability can be difficult to
maintain.

• Cryptocurrency exchanges are
digital platforms that allow users
to buy, sell, and trade various
cryptocurrencies.
• Users can create accounts and
deposit funds using fiat currency
or cryptocurrencies.
• Cryptocurrency exchanges charge
fees for their services, which can
vary depending on the exchange
and transaction.
• Cryptocurrency exchanges are not
regulated in the same way as
traditional stock exchanges, which
can make them riskier for investors
• It's important to carefully research and choose a
reputable exchange before investing in
cryptocurrencies.

12. Advantage of Cryptocurrency
• Decentralization: Cryptocurrencies are decentralized, meaning they are not controlled by a
central authority like a government or bank. This gives users greater control over their
money and eliminates the need for intermediaries, which can lead to faster and cheaper
transactions.
• Security: Cryptocurrencies use advanced encryption techniques to secure transactions and
protect user privacy. This makes them more resistant to fraud and hacking than traditional
payment methods.
• Transparency: Cryptocurrencies use a public ledger called the blockchain, which allows
anyone to see all transactions that have taken place. This helps prevent fraud and increases
trust in the system
• Accessibility: Cryptocurrencies can be used by anyone with an internet connection,
regardless of their location or financial status. This makes them especially useful for people
who do not have access to traditional banking services.
• Lower transaction fees: Cryptocurrencies typically have lower transaction fees than
traditional payment methods, which can be especially beneficial for large transactions.
• Innovation: The use of cryptocurrencies has led to the development of new technologies
and financial instruments, such as smart contracts and decentralized finance (DeFi)
applications, that have the potential to revolutionize the financial industry

13. Disadvantage of Cryptocurrency
• Volatility: Cryptocurrencies can be highly volatile, with prices fluctuating rapidly and
unpredictably. This can make them risky investments and may discourage their use as a
stable store of value.
• Lack of regulation: Cryptocurrencies are not regulated by governments or central authorities,
which can make them more susceptible to fraud and scams.
• Limited acceptance: Cryptocurrencies are not widely accepted as a form of payment, which
can limit their usefulness in daily transactions.
• Potential for illegal activities: Cryptocurrencies can be used for illegal activities such as
money laundering and illegal purchases on the dark web
• Technical challenges: Cryptocurrencies require a certain level of technical knowledge to use
and store securely. Loss of private keys or other technical issues can result in the permanent
loss of funds.
• Energy consumption: Cryptocurrency mining and transactions can consume significant
amounts of energy, which can have a negative impact on the environment.
• Lack of recourse: If a cryptocurrency transaction is lost or stolen, there may be no way to
recover the funds as there is no central authority to intervene.

14. Conclusion
• In conclusion, cryptocurrency has several potential advantages,
including decentralization, security, transparency, accessibility, cost
efficiency, and potential for innovation. However, it also comes with
potential risks and disadvantages, such as volatility, lack of regulation,
limited acceptance, potential for illegal activities, technical
challenges, energy consumption, and lack of recourse in case of loss
or theft. As with any investment or financial technology, it is
