What is a bitcoin?
Essentially a bitcoin is a digitally stored unit of value that can be transferred between users of the bitcoin network. When one user transfers a unit to another unit a digitally encrypted message is transmitted across the network of computers and if enough of these machines agree that it is a unique transaction it is confirmed.
Where do bitcoins come from?
Bitcoins are generated through a process called “mining”. Mining involves checking for a solution to a digital puzzle. Each time a batch of bitcoins is mined the next solution is much harder to find than the last thus ensuring it would not be possible to make lots of them in one go and destroying their value.
Who invented bitcoins?

What is so good about bitcoins?
Bitcoins represent a way of transferring capital around the world cheaply, quickly and currently anonymously. However, the recent revelations about national governments (Especially the USA) snooping on internet traffic and the fact that the blockchain (a shared database of all transactions) is available for all to look at may compromise the anonymity of the service.
I have heard that bitcoins are bad as people use them to do illegal things with. Is this true?
That is subjective. Until the advent of bitcoins the United States dollar was the currency of choice for illegal transactions. Dollars aren’t bad are they? Gold can also be used anonymously – but is just much harder to move around than bitcoins.
What can I do with a bitcoin?
You can transfer it to someone else or keep it. More and more businesses are starting to accept bitcoins as payment for goods and services. Richard Branson recently announced that he would accept bitcoins for a trip on his new Virgin Galactic service to the edge of space.
Why can’t a bitcoin be forged?
The fact so many different individuals are part of the network and own bitcoins makes it very difficult to ‘double spend’ coins. There is such a thing as a 51% attack whereby one individual manages to get control of 51% of the network. In the event they did this they could do as they liked with bitcoins. As more people get involved this becomes increasingly more difficult.
What is going to happen to bitcoins?
The truth is nobody knows. They could replace money in the majority of transactions in which case they will become incredibly valuable or there could be an as yet unnoticed flaw in the system that renders them completely worthless. Both arguments are at this stage equally valid. However, no matter what happens I believe that bitcoins have already changed the world.
