What is Bitcoin?
• Bitcoin can be used to buy or sell items from people and companies that
accept bitcoin as payment, but it differs in several key ways from
traditional currencies.

• In Bitcoin,Transactions are made with no middle men – meaning, no
banks!
• It is a form of digital currency (physical form is absent), created and held
electronically.

• There is many digital currency like ripple,etherum,litecoin etc,but Bitcoin
is more used.

Why is Bitcoin created?
• Bitcoin is decentralised virtual currency that provides secure global
transactions very quickly and does not have any third-party manipulation.

• Explore investment Opportunities in the world’s fastest growing economy.

• Bitcoin is the part of Block chain.

• If we want to send money in foreign then we face to many problems like
interferences of multiple bank,transected only business hours,additional
fees to transfer money and it takes more time.

• To solve these all problems Bitcoin is created.

• In Bitcoin no third party required,no additional fees required,and
transaction can be done very fast and it is secure also.

How did Bitcoin get started?
• On October 31st, 2008, “Bitcoin: A Peer-to-Peer Electronic Cash System”
was posted to a cryptography mailing list, published under the name
“Satoshi Nakamoto”. The whitepaper outlined the foundation of how
Bitcoin would operate.

• On August 18, 2008, an unknown person or entity registered the
Bitcoin.org domain.

• On January 8th, 2009, the first version of Bitcoin is announced, and
shortly thereafter, Bitcoin mining begins.

• It described a sytem of cryptocurrency that was not backed by any
government or any form of existing currency.

• Interestingly, there is no such person. It’s a pseudonymn

Why does Bitcoin have value?
• Bitcoins are like diamonds or gold – no intrinsic value.

• As more people want to buy Bitcoins, sellers will charge more.

• It’s a free market and as wild as you can imagine.

• No rules, regulations or oversight.

• Speculators who think Bitcoins will be successful, buy as many as they
can and hold them price appreciation.

• If 21 million Bitcoins are in circulation and current price is $500, then
total market value is ~$10 Billion.

How does Bitcoin work?
• A transaction is a transfer of value between Bitcoin walletsthat gets
included in the block chain.

• Bitcoin wallets keep a secret piece of data called a Private key or seed,
which is used to sign transactions, providing a mathematical proof that
they have come from the owner of the wallet.

• The signature also prevents the transaction from being altered by anybody
once it has been issued.

• All transactions are broadcast to the network and usually begin to be
confirmed within 10-20 minutes, through a process called mining.

• Bitcoin technology is worked on Blockchain technology.

• Blockchain technology is combination of three technology
1) private key cryptography
2) a distributed network with
a shared ledger
3) an incentive to service the network’s
transactions,record-keeping and security.

• these technologies work together to secure digital relationships.

Cryptographic keys
• Two people wish to transact over the internet.

• Each of them holds a private key and a public key.

• The main purpose of this component of blockchain technology
is to create a secure digital identity reference.

• Identity is based on possession of a combination of private and
public cryptographic keys.

• The combination of these keys can be seen as a dexterous form
of consent, creating an extremely useful digital signature.

• In turn, this digital signature provides strong control of ownership.

• But strong control of ownership is not enough to secure digital
relationships. While authentication is solved, it must be combined with a
means of approving transactions and permissions (authorisation).

• For blockchains, this begins with a distributed network.

Distributed Network
• Much of the value of the bitcoin blockchain is that it is a large network
where many user or validators.

• In ,there is use of mathematical verification in blockchain.

• the size of the network is important to secure the network.

• That is one of the bitcoin blockchain’s most attractive qualities — it is so
large and has amassed so much computing power.

• When cryptographic keys are combined with this network, a super useful
form of digital interactions emerges.

• The process begins with A taking their private key, making an
announcement of some sort — in the case of bitcoin, that you are sending
a sum of the cryptocurrency — and attach it to B’s public key.

INCENTIVE SERVICE
• This technology is very insentive serivce for transaction ,record keeping
and security.

• So many people use this technology.

• In future,bitcoin may be take place of all bank transaction.

• It is very easiest technology.

How can we earn Bitcoin?
• Earn Bitcoins by accepting them as a means of payment
• Earn free Bitcoins by completing tasks on websites
• Earn Bitcoins from interest payments %
• Earn Bitcoins from mining
• Earn Bitcoins by getting tipped
• Earn Bitcoins through trading
• Earn Bitcoins as a regular income
• Earn Bitcoins from gambling – not suitable for everyone

Advantages of Bitcoin
• It is decentralized
• It is easy to set up and it is fast
• It is anonymous
• It is completely transparent
• Transaction fees are miniscule
• Transactions are irreversible

Disadvantages of Bitcoin
• New and uninvestigated financial product
• History is full of illegal and questionable activity
• Absence of relevant theoretical background
• Highly volatile value and an unknown issuer
• Undefined legal status
• Unregulated commodity and absence of consumer protection
• Anonymity and blurry taxation status
• Illegal or undefined in most countries of the world
