Bitcoin is actually a private, unregulated currency. The more users, the more transactions and conversions in other currencies, the more fluid the market is.
Bitcoin is increasingly in the news, banks and companies are starting to embrace Bitcoin as a way to pay / receive.
To start Bitcoins is simple: open a wallet on e.g. Blockchain.info: install the app on your mobile, tablet computer, you can use a QR code to easily “pair” the device with the wallet. Now buy some bitcoins in an exchange (e.g. via PayPal account or CC) It is child’s play! Now find anyone that can or want to exchange money…
PS It is my intention to further explain specific aspects of Bitcoin in future posts.
