presention about crypto currencies and bitcoins. A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets.

3. What is Crypto currency?
Crypto currencies are just lines of computer code that hold
monetary value. Those lines of code are created by electricity and
high-performance computers.
Crypto currency is also known as digital currency. Either way, it is a
form of digital public money that is created by mathematical
computations and policed by millions of computer users called
'miners'. Physically, there is nothing to hold.

4. No Government Control
• Governments have no control over the creation of crypto
currencies, which is what initially made them so popular.
• Most crypto currencies begin with a market cap in mind, which
means that their production will decrease over time thus, ideally,
making any particular coin more valuable in the future.

5. Bitcoins
• Bitcoin was the first cryptocoin currency ever invented. No one
knows exactly who created it – cryptocurrencies are designed for
maximum anonymity – but bitcoins first appeared in 2009 from a
developer supposedly named Satoshi Nakamoto.

6. How Will you Mine Crypto currency?
• A free private database called a coin wallet. This is a password-
protected container that stores your earnings and keeps a network-wide
ledger of transactions.
• A free mining software package.
• A membership in an online mining pool, which is a community of miners
who combine their computers to increase profitability and income
stability.
• Membership at an online currency exchange, where you can exchange
your virtual coins for conventional cash, and vice versa.
• A reliable full-time internet connection, ideally 2 megabits per second or
faster speed.

7. How Will you Mine Crypto currency?
• A hardware setup location in your basement or other cool and air-conditioned
space.
• A desktop or custom-built computer designed for mining. Yes, you may use your
current computer to start, but you won't be able to use the computer while the
miner is running. A separate dedicated computer is ideal.
• An ATI graphics processing unit (GPU) or a specialized processing device called a
mining ASIC chip. The cost will be anywhere from $90 used to $3000 new for
each GPU or ASIC chip. The GPU or ASIC will be the workhorse of providing the
accounting services and mining work.
• A house fan to blow cool air across your mining computer. Mining generates
substantial heat, and cooling the hardware is critical for your success.
• There are ongoing technology changes and new techniques for optimizing coin
mining results. The most successful coin miners spend hours every week
studying the best ways to adjust and improve their coin mining performance.

8. Transaction Process
• Every transactions ever happened recorded on one global ledger in
crypto currency.
• Sender initiate a bitcoin payment using "wallet" software. This and other
pending transactions are broadcast on the global bitcoin network.
• Once every ten minutes or so, miners specialized computers (or groups
of computers) on this network, collect a few hundred transactions and
combine them in a "block".
• In order to mine a block and validate the transaction, miners compete to
solve a difficult mathematical equation (a "hash function"). The miner
that solves the equation first further processes the block and broadcasts
this "proof-of-work" to the bitcoin network.

10. Difference between Conventional and Crypto
Currency
Conventional Currency Crypto currency
Type Real Physical
Intermediates Yes No
Portability Yes Yes (Highly Portable)
Durable Moderately Durable Highly Durable
Acceptance National Global(Works Anywhere in
the world)
Decentralized No (central Bank controls) Yes

11. Why use Crypto currency?
• Fast and cheap
• Easy to use.
• Free to transfer and hold.
• Decentralized control- users are the only owner of cryptocurrency.
• Central government can’t take it away and there are no
chargebacks.
• Privacy and Security – Anonymous payments
