What is Bitcoin mining?

As mentioned in an earlier section, one can think of Bitcoin as one big global ledger system that records transactions (or ‘moving money’) between one person to another. Whenever Bitcoin transactions are processed on the Bitcoin network – that means Bitcoin is moved from one person to another – someone has to make sure all the transactions are recorded properly and that the ledgers on all the systems are synchronized all over the world.

How Bitcoin Mining Works

When you hear about bitcoin "mining," you envisage coins being dug out of the ground.

But bitcoin isn't physical, so why do we call it mining?
Because it's similar to gold mining in that the bitcoins exist in the protocol's design (just as the gold exists underground), but they haven't been brought out into the light yet (just as the gold hasn't yet been dug up). The bitcoin protocol stipulates that 21 million bitcoins will exist at some point. What "miners" do is bring them out into the light, a few at a time.
They get to do this as a reward for creating blocks of validated transactions and including them in the blockchain.

Is Bitcoin used by criminals?

There is often public misconception that Bitcoin is mostly used by criminals, but nothing could be further from the truth. This is mainly because many people think Bitcoin is anonymous, when in fact it’s the opposite - all Bitcoin transactions are transparent for the whole world to see. People might not be able to link the identity to Bitcoin right away (that is also why it is sometimes called ‘pseudo anonymous’), but once they do, they can track everything you’ve ever done on the Bitcoin network. This makes it a particularly bad tool for illicit use.

While Bitcoin might actually turn out to be one of the safest and least ‘bad’ ways to use money, it doesn’t mean that criminals don’t use it. Just like normal money, they do. But there are two important things to note - firstly, that as more data becomes available in the industry, the more it is becoming clear the number of bad uses is very, very minute - if the entire Bitcoin ecosystem is represented by a big mountain, the size of the bad parts is a couple of rocks. Second, that in any financial system, this is a risk that can never be eliminated, merely mitigated, and Bitcoin has some of the best tools in the world for that.

How do I get Bitcoin?
