• “Miners” – supply Bitcoin network with computing power needed to maintain the
security of the block chain (a distributed technology that acts as Bitcoin’s ledger)
• Every single Bitcoin carries the entire history of the transactions it has undergone, and
any transfer from one owner to another becomes part of the code
• Bitcoin is stored in such a way that the new owner is the only person allowed to spend
it.
• Miners are rewarded with “blocks” of issued bitcoins (a “block” currently contains 25
bitcoins); this is how currency is issued
• Price of Bitcoin fluctuates wildly. As of April 23, 2013, 1 bitcoin is worth $130 USD
