Bitcoin trading: Bitcoin is a cryptocurrency and a new and unique financial vehicle, unlike anything the world has ever seen. It’s called a cryptocurrency because it uses cryptography to control the creation and transfer of money. Despite the name, there is no physical coin to speak of, Bitcoin is a completely electronic form of money. Bitcoin solves the so called ‘’double spending problem’’ present with digital goods. For example, if I have an mp3 file or an ebook on my computer, I can freely copy that file a thousand times and send it to a thousand different people. For a digital currency, the possibility for unlimited copying would mean a quick hyperinflationary death. Bitcoin solves this by maintaining a peer to peer network and recording each transaction in a public ledger called the block chain. Say I send 1 bitcoin from my bitcoin address to my friend John. The bitcoin network records that transaction in the block chain and I no longer have possession of that bitcoin. The coin ‘’moved’’ from my bitcoin wallet to John’s wallet. 60049
