3. Cryptocurrency
A cryptocurrency is a digital asset designed to work as a medium of
exchange wherein individual coin ownership records are stored in
a ledger existing in a form of computerized database using strong
cryptography to secure transaction records, to control the creation of
additional coins, and to verify the transfer of coin ownership.
It typically does not exist in physical form (like paper money) and is
typically not issued by a central authority.

4. Decentralized Ledger
Cryptocurrencies typically use decentralized control as opposed to centralized digital
currency and central banking systems. When a cryptocurrency is mined or created
prior to issuance or issued by a single issuer, it is generally considered centralized.
When implemented with decentralized control, each cryptocurrency works
through distributed ledger technology, typically a blockchain, that serves as a public
financial transaction database.

5. Introduction to Bitcoin
Who made Bitcoin?
Bitcoin is a cryptocurrency invented in 2008 and
launched in 2009 by someone (or a group of
people) that goes by the pseudonym Satoshi
Nakamoto.

6. Reasons for the rise of Bitcoin
Why Bitcoin started? It was created in the wake of the 2008 global financial crisis as a way for people to control their money
themselves, without having to rely on companies, banks, or governments and their fees and controls.

7. Facts about Bitcoin
There are only 21 million
bitcoins that can be mined in total.
Total Bitcoins
Bitcoin itself is very difficult to hack, and
that is largely due to the blockchain
technology which supports it.
Bitcoin Security
More than 90% Bitcoins are already
mined.
Bitcoins Mined
The final Bitcoin is unlikely to
be mined until around the year 2140.
100% Bitcoins Mined
1 Bitcoin is equal to 32,44,963.86 INR
and in UD Dollar 44,499.90 $.

8. Bitcoin Mining & Miners
Bitcoin mining is painstaking, costly, and only sporadically rewarding. But, by
mining you can earn Bitcoins without having to put down money for it.
You need either a GPU (graphics processing unit) or an application-
specific integrated circuit (ASIC) in order to set up a mining rig.
Bitcoin miners receive Bitcoin as a reward for completing "blocks" of verified
transactions which are added to the blockchain.
Mining rewards are paid to the miner who discovers a solution to a
complex hashing puzzle first, and the probability that a participant will
be the one to discover the solution is related to the portion of the total
mining power on the network.
Bitcoin mining is the process of creating new Bitcoin by solving a computational
puzzle, and the computers who are solving these computational puzzles are
miners.

9. Blockchain Technology
Blockchain is a system of recording information in a way that makes it difficult
or impossible to change, hack, or cheat the system.
A blockchain is essentially a digital ledger of transactions that is duplicated and
distributed across the entire network of computer systems on the blockchain.

11. Altcoin refers to all
digital cryptocurrency launched
following the success of Bitcoin.
hence the name, which means
“alternative to Bitcoin”.
There are over 900 Altcoin
currencies that have been created
since Bitcoin.
Alt-Coins

12. Other Cryptocurrencies
Diem (Libra)
Ether
Ripple
Litecoin
Stable Coins
Diem (formerly known
as Libra) is proposed
by Facebook.
The plan also includes
a private
currency implemented as
a cryptocurrency.
The currency and network
do not yet exist. The launch
was planned to be in 2021.
It was launched in 2015.
It is based on Ethereum
Technology.
It uses smart contract to
guaranty of a transaction.
It takes 25 sec for block
creation.
It was launched in 2012.
It offers Interoperability
between different
financial systems.
It takes less than 4 sec in
block creation.
Ripple Collaborates with
American Express and
Bank of America.
It was launched in 2011.
Total supply is 84 million.
Block creation time is
then Bitcoin. In Bitcoin it
takes 10 min and in
Litecoin in take 2.5 min
Stablecoins are
cryptocurrencies
designed to minimize the
volatility of the price of
the stablecoin, relative to
some "stable" asset or
basket of assets. A
stablecoin can be
pegged to a
cryptocurrency, fiat
money, or to exchange-
traded commodities.

13. Cryptocurrency in India (History)
An earlier bill in 2019 reportedly sought to ban cryptocurrency and criminalize
its possession in India. However, it was not introduced.
.
Moreover, the Reserve Bank of India (RBI) had banned cryptocurrencies in
2018, which was later overturned by the Supreme Court of India in March 2020

14. Cryptocurrency in India (Present)
RBI said that it is seriously thinking about developing
a sovereign digital currency in the country and will be
releasing it appropriately. However, the RBI’s stance
on the ban of private cryptocurrency still remains the
same.
The governor of RBI Shaktikanta Das said that the
cryptocurrency issuance is a sovereign mandate and
will not be handed over to a private company, as there
is a huge challenge around money laundering.

15. Positive of Cryptocurrency
Currency exchanges can be done easily
Cryptocurrency can be bought using many currencies
like the US dollar, European euro, British pound, Indian
rupee or Japanese yen. With the help of different
cryptocurrency wallets and exchanges, one currency can
be converted into the other by trading in cryptocurrency,
across different wallets, and with minimal transaction
fees.
Cost-effective mode of transaction
One of the major uses of cryptocurrencies is to send money
across borders. With the help of cryptocurrency, the
transaction fees paid by a user is reduced to a negligible or
zero amount. It does so by eliminating the need for third
parties, like VISA or PayPal, to verify a transaction. This
removes the need to pay any extra transaction fees.
A fast way to transfer funds
Cryptocurrencies have always kept itself as an optimal
solution for transactions. Transactions, whether
international or domestic in cryptocurrencies, are
lightning-fast. This is because the verification requires
very little time to process as there are very few barriers
to cross.
Protection from inflation
Inflation has caused many currencies to get their value
declined with time. Almost every cryptocurrency, at the
time of its launch, is released with a fixed amount. The
source code specifies the amount of any coin, like, there
are only 21 million Bitcoins released in the world. So, as
the demand increases, its value will increase which will
keep up with the market and, in the long run, prevent
inflation.
Self-governed and managed
Governance and maintenance of any currency is a major
factor for its development. The cryptocurrency transactions
are stored by developers/miners on their hardware, and
they get the transaction fee as a reward for doing so. Since
the miners are getting paid for it, they keep transaction
records accurate and up-to-date, keeping the integrity of the
cryptocurrency and the records decentralized.
Secure and private
Privacy and security have always been a major concern
for cryptocurrencies. The blockchain ledger is based on
different mathematical puzzles, which are hard to
decode. This makes a cryptocurrency more secure than
ordinary electronic transactions. Cryptocurrencies, for
better security and privacy, use pseudonyms that are
unconnected to any user, account or stored data that
could be linked to a profile.

16. Negative of Cryptocurrency
Some coins not available in other fiat currencies
Some cryptocurrencies can only be traded in one or a few fiat
currencies. This forces the user to convert these currencies
into one of the major currencies, like Bitcoin or Ethereum first
and then through other exchanges, to their desired currency.
This applies to only a few cryptocurrencies. By doing this, the
extra transaction fees are added in the process, costing
unnecessary money.
Adverse Effects of mining on the environment
Mining cryptocurrencies require a lot of computational power and
electricity input, making it highly energy-intensive. The biggest
culprit in this is Bitcoin. Mining Bitcoin requires advanced computers
and a lot of energy. It cannot be done on ordinary computers. Major
Bitcoin miners are in countries like China that use coal to produce
electricity. This has increased China’s carbon footprint
tremendously.
No refund or cancellation policy
If there is a dispute between concerning parties, or if
someone mistakenly sends funds to a wrong wallet
address, the coin cannot be retrieved by the sender. This
can be used by many people to cheat others out of their
money. Since there are no refunds, one can easily be
created for a transaction whose product or services they
never received.
Can be used for illegal transactions
Since the privacy and security of cryptocurrency
transactions are high, it’s hard for the government to
track down any user by their wallet address or keep tabs
on their data. Bitcoin has been used as a mode of
exchanging money in a lot of illegal deals in the past,
such as buying drugs on the dark web. Cryptocurrencies
are also used by some to convert their illicitly obtained
money through a clean intermediary, to hide its source.
Data losses can cause financial losses
The developers wanted to create virtually untraceable
source code, strong hacking defenses, and impenetrable
authentication protocols.
This would make it safer to put money in cryptocurrencies
than physical cash or bank vaults. But if any user loses the
private key to their wallet, there’s no getting it back. The
wallet will remain locked away along with the number of
coins inside it. This will result in the financial loss of the
user.
Decentralized but still operated by some organization
The cryptocurrencies are known for its feature of being decentralized.
But, the flow and amount of some currencies in the market are still
controlled by their creators and some organizations. These holders
can manipulate the coin for large swings in its price. Even hugely
traded coins are susceptible to these manipulations like Bitcoin,
whose value doubled several times in 2017.

17. Should you invest in Bitcoin?
Cryptocurrency is a extremely volatile currency. In my
opinion, you should invest that much amount of money
that you can afford to loose. Do not take loans for
investment in cryptocurrencies.
It is pretty clear that it is both an opportunity as well as
risk.

18. Conclusion
Overall, it can be said that cryptocurrencies and Bitcoins could play an
important role in the future of finance.
It remains to be seen whether cryptocurrency can become a medium of
exchange that will be subject to widespread use or will it remain a store of
value investment?
Will you be able to buy bread and eggs from your nearby shops with
Bitcoins in the future? or will it not be possible?
That day might be very far but it cannot be ruled out as impossible that
easily.
