1. What is Bitcoin
Bitcoin is a digital currency designed by Satoshi
Nakamoto. Bitcoin allows users to send payments within a
decentralized,peer-to-peer network, and is unique in that it does not require a
central clearing house of financial institution clearing transactions. Users
must have an internet connection and Bitcoin software to make payments to
another public account/address.
2. Satoshi is the smallest unit of Bitcoin; 1
Bitcoin contains 100 million Satoshi. By design, the supply of Bitcoins cannot
exceed 21 million Bitcoins(2,100 trillion Satoshi). The total amount of Bitcpin
in circulation will increase predictably, based on its underlying code, until
reaching the cap in 2140.
3. A public history of all transactions is
continuously updated and verified by "miners" who gather batches of new
transactions into blocks and attach these blocks to the end of "Blockchain".
4. Bitcoin supply is increased with every new block of transactions added to
the public history.
5. Money/currencies are generally thought to have three
distinct roles: as a unit of account, medium of exchange, and store of
value.
6. as a medium of exchange, Bitcoin is attractive as it offers low
transaction costs.
7. Bitcoin offers an attractive alternative to cash in
terms of security, transparency of transactions, and counterfeiting.
8.
Bitcon‘s role as a store of value is seriously compromised by its elevated price
volatility.
