What is Bitcoin? Why are people interested in it? Isn't it a scam?
Bitcoin was the first cryptocurrency ever created. It is a 'coin' (currency) that is entirely digital, so therefore made up of data 'bits': Bitcoin. It was invented by someone pseudonominously named 'Satoshi Nakamoto' in 2009, as a direct reaction to the financial crisis of 2008. Satoshi's vision was to create a monetary system that was entirely decoupled from a traditional, centralised financial system (i.e. no banks).
This is the reason that Bitcoin is referred to as a decentralised asset: the asset itself is not stored in one central place and then distributed (such as, crudely, a bank with it's millions locked away in its vaults, which are then centrally distributed to customers); rather, the asset is stored remotely across the entire network of people owning and trading it - in this way, there is no 'third' party here.
Why is this important? Well, let's just *suppose* that a bank gets into financial difficulty (think 2008) and eventually collapses (government doesn't bail it out in this example). What's happened to your money? It's gone. It was stored centrally by the bank; the bank no longer exists; 'your' money is no longer yours.
This cannot happen with a decentralised asset such as Bitcoin, because there is no centralised bank: it is distributed and stored by everyone interacting with it, through the cryptographically-secure blockchain.
So Bitcoin is essentially a two-fingered salute at the banking system? So what? Well - partly this is true. Proponents of Bitcoin see the decentralised aspect as one of it's key draws. However, this isn't it's only benefit. Most significantly, it is becoming seen as a genuine hedge against 'fiat' (traditional currency) devaluation.
Over time, fiat currencies naturally succumb to devaluation: put simply, as more physical money is printed by successive governments (sometimes euphemistically known as 'quantative easing') the overall purchasing power of that currency naturally decreases over time: the more there is of something, the less it is worth.
This is why £10 forty years ago would have comfortably bought you several rounds in a London pub with some change to spare, whereas now it'd get you a single pint and a packet of crisps if you were damn lucky.
- Cryptocurrency is a digital, cryptographic store of value.
- Bitcoin is one such crypto, created in 2008.
- Bitcoin is a decentralised store of value, distributed on the blockchain
- Bitcoin is finite (21 million) and the amount released (mined) is halved every four years
- In this sense, Bitcoin can be seen as a deflationary asset and a hedge against the inflationary fiat currency system
- Due to the above factors, the value of Bitcoin rises exponentially every four years
