The document provides an overview of Bitcoin, including: - Bitcoin is a decentralized digital currency created by Satoshi Nakamoto in 2008. - It works using a peer-to-peer network and blockchain technology to record all transactions. - Users can buy, sell, and trade bitcoins through exchanges or person-to-person using digital wallets stored on their devices or in the cloud. - While Bitcoin offers anonymity and lack of oversight, it also faces risks of volatility, limited acceptance, and potential use for illicit activities.

3. Introduction
 Bitcoin is a
worldwide cryptocurrency and
digital payment system called
the first decentralized digital
currency.
 Bitcoin is an innovative
payment network and a new
kind of money.
 Bitcoin offers the promise of
lower transaction,startups or
usage fees as compared to
others.

4.  Bitcoin uses peer-to-peer
technology to operate .
 Bitcoin is open-source i.e. Its
design is public so everyone
can participate in the Bitcoin
system for transactions
needing an exchange of
payment.

5.  There are no physical Bitcoins, only
balances associated with public and private
keys.
 These balances are kept on a public ledger,
along with all Bitcoin transactions.
 The public network itself manages
transactions and the issuing of
Bitcoins.

7. Who created Bitcoin?
 The original Bitcoin code was designed by
Satoshi Nakamoto under MIT open source
credentials.
 In 2008 Nakamoto outlined the idea behind
Bitcoin in his White Paper.
 Satoshi left the Bitcoin code in the hands of
developers and the community in 2010.
 Thus far hundreds of developers have added
to the core code throughout the years.

8. HOW DOES BITCOIN WORKS

9. Download bitcoin

Buy bitcoins(between
individual and
exchange)
Mine bitcoin
(50 bitcoins per math
problem)
Use at discount
chains,shopping
malls,hotels.

10.  Bitcoin wallet
enables a user to
send and receive
bitcoins.
 Behind the scenes,
the Bitcoin
network is sharing
a massive public
ledger called the
"block chain".
 This ledger
contains every
transaction ever
processed.

11. Why Bitcoins?
 Users Anonymity: Bitcoin
purchases are discrete. User’s
Bitcoin purchases are never
associated with his personal
identity .
In fact, the anonymous Bitcoin
address that is generated for user
purchases changes with each
transaction.
 Purchases Are Not Taxed: sales
taxes are not added into any bitcoin
purchases.
 International payments are easy
and cheap: As bitcoins are not tied
to any country and low transaction
fees.User has complete control on
his money.

12. Anonymity (गुमनामी)
 Though each bitcoin transaction is
recorded in a public log, names of
buyers and sellers are never
revealed – only their wallet IDs.
 While that keeps bitcoin users’
transactions private, it also lets
them buy or sell anything without
easily tracing it back to them.
 That’s why it has become the
currency of choice for people who
buy drugs online or other illicit
activities.

13. Bitcoin address
• Bitcoin is a type of cryptocurrency:
Balances are kept using public and
private "keys“, which are long
strings of numbers and letters
linked through the
mathematical encryption algorithm
that was used to create them.
• The public key (comparable to a
bank account number) serves as
the address which is published to
the world and to which others may
send bitcoins.
• The private key (comparable to an
ATM PIN) is meant to be a
guarded secret, and only used to
authorize Bitcoin transmissions.

bitcoins to each

similar to sending
cash digitally.

Internet, anyone can help to verify
and record payments into the block
chain. This process is called
mining.
 Miners are rewarded with newly
created bitcoins and transaction
fees.

20.  People compete to
“mine” bitcoins using
computers to solve
complex math puzzles.
 This is how bitcoins
are created.
 Miners receive 12.5
bitcoins every 10
minutes.
 Currently, a winner is
rewarded with 25
bitcoins roughly every

24. ACCEPTANCE OF BITCOIN

25. Blockchain
 Mining involves adding
bitcoin transaction data to a
shared public ledger of past
transactions on which the
entire Bitcoin network relies
called blockchain.
Each group of transactions is
called a block.
With the blockchain all
transactions are logged with
the time, date, participants and
the amounts of transaction.

26. Where are bitcoins kept?

computer.
 The wallet is a kind
of virtual bank
account that allows
users to send or
receive bitcoins, pay

their money..

31. Who controls the Bitcoin network?
 Nobody owns the Bitcoin network much like no one
owns the technology behind email or the Internet.
 Bitcoin transactions are verified by Bitcoin
miners which has an entire industry and Bitcoin cloud
mining options.
 While developers are improving the software they
cannot force a change in the Bitcoin protocol because all
users are free to choose what software and version they
use.

 Untraceable
This feature of Bitcoin of also
attracts crime. People can buy
and sell drugs and other illegal
items with significantly less risk
of being traced by authorities. .
 Hard to trade
You can't just use a credit card
to buy Bitcoins online
specifically .
untraceable
Hard to
trade
Still too
new
Cant buy
all the stuff
Too volatile

37.  Still too new
Bitcoin is only a few years old. It's possible
that a competing crypto currency becomes
more successful than Bitcoin or that
somebody somehow finds a major flaw in the
system. We don't have decades of history
yet.
 Can't buy all stuff
There aren't a lot of places where Bitcoins
are accepted as payment. This is likely to
change, but for now the average person will
mostly buy Bitcoins as investment.
 Too volatile
Currently Bitcoin prices are going up like
crazy.Currently the price is going up so fast a
webshop would have to adjust their prices
almost daily if they wanted to accept
Bitcoins. It's not very convenient.

38. Ways to Earn Bitcoins
 Receiving As Payment
Bitcoins can be accepted as a means of payment
for products sold or services provided.
 Working For Them
Those who are self-employed can get paid for a
job in bitcoins. Coinality features jobs – freelance,
part-time and full-time – that offer payment in
bitcoins, as well as Dogecoin and Litecoin.
 Interest Payments
Another interesting way (literally) to earn bitcoins
is by lending them out, and being repaid in the
currency
 Gambling
It’s possible to play at casinos that cater to Bitcoin
aficionados, with options like online lotteries,
jackpots, spread betting and other games.

39. Bitcoin in existence
 21 million bitcoins
There are only 21 million bitcoins that can ever be
mined, regardless of the earth's population and its
corresponding demand for bitcoins. Once all 21 million
have been mined, there will never be any new bitcoins
(unless a change to the protocol is made to increase the
supply)
 Bitcoin is unique in that only 21 million bitcoins will ever
be created. However, this will never be a limitation
because transactions can be denominated in smaller
sub-units of a bitcoin, such as bits - there are 1,000,000
bits in 1 bitcoin. Bitcoins can be divided up to 8 decimal
places (0.000 000 01) and potentially even smaller units if
that is ever required in the future as the average
transaction size decreases.
