The document provides an overview of cryptocurrency, defining it as a digital asset that utilizes cryptography for secure transactions. It discusses the contrasts between conventional and digital currencies, highlights risks such as hacking and scams, and gives an example of Bitcoin, its technology, and transaction process. The conclusion suggests that while cryptocurrencies are notable innovations, they may not entirely replace traditional fiat currencies and provoke important economic questions.

3. What is Cryptocurrency?
A cryptocurrency (or crypto currency) is a
digital asset designed to work as a medium of
exchange using cryptography to secure the
transactions and to control the creation of
additional units of the currency.

6. Why use Cryptocurrency?

7. Risks
•Hackers. Cryptocurrencies are targets for highly sophisticated
hackers, who have been able to breach advanced security systems.
•Fewer protections. If you trust someone else to hold your
cryptocurrencies and something goes wrong, that company may not
offer you the kind of help you expect from a bank or debit or credit
card provider.
•Cost. Cryptocurrencies can cost consumers much more to use than
credit cards or even regular cash, often due to price volatility.
•Scams. Fraudsters are taking advantage of the hype surrounding
virtual currencies to cheat people with fake opportunities.
•Lack of Transparency. The anonymous nature of cryptocurrencies
make transparency and accountability difficult for consumers seeking
to ensure the safety of their investments.

8. Types of Cryptocurrency

9. Example : Bitcoin
• Both a cryptocurrency and an electronic payment system
• Satoshi Nakamoto in 2008
• First decentralised payment network
• System is peer-to-peer
• 21 million bitcoins
• Completely Open source
• 1BTC = $1258.48

13. Conclusion
Cryptocurrency is an impressive technical achievement, but it remains a
monetary experiment. Even if cryptocurrencies survive, they may not fully
displace fiat currencies. As I have tried to show in this presentation, they provide
an interesting new perspective from which to view economic questions
surrounding currency governance, the characteristics of money, the political
economy of financial intermediaries, and the nature of currency competition.
