What is Bitcoin?
Bitcoin is a digital currency also called crypto-currency that is not backed by any country's central bank or government. Bitcoins can be traded for goods or services with vendors who accept Bitcoins as payment. Bitcoin-to-Bitcoin transactions are made by digitally exchanging anonymous, heavily encrypted hash codes across a peer-to-peer P2P network. The P2P network monitors and verifies the transfer of Bitcoins between users. Each user's Bitcoins are stored in a program called a digital wallet , which also holds each address the user sends and receives Bitcoins from, as well as a private key known only to the user.
The Bitcoin network is designed to mathematically generate no more than 21 million Bitcoins and the network is set up to regulate itself to deal with inflation. Bitcoins can be spent by initiating a transfer request from a Bitcoin address in the customer's wallet to a Bitcoin address in the vendor's wallet.
In the United States, Bitcoins are controversial because they can be used to anonymously transfer illicit funds or hide unreported income from the Internal Revenue Service IRS. Bitcoin policy now requires transactions that involve traditional, government-backed currencies to be attached to an identity. Please check the box if you want to proceed.

The authenticity of each transaction is protected by digital signatures corresponding to mezn sending addresses, allowing all users to have full control over sending bitcoins from their own Bitcoin addresses. In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. This is often called "mining". To learn more about Bitcoin, you can consult the dedicated page and the original paper.

Attempting to assign special bittcoin to a local authority in the rules of the global Bitcoin network is not a practical possibility.
Any rich organization could choose to invest in mining hardware to control half of the computing power of the network and become able to block or reverse recent transactions. However, there is no guarantee that they could retain this power since this requires to invest as much than all other miners in the world. It is however possible to regulate the use of Bitcoin in a similar way to any other instrument.
Just like the dollar, Bitcoin can be used for a wide variety of purposes, some of which can be considered legitimate or not as per each jurisdiction's laws.
