Bitcoins: it's origin and it's decentralized system.

The most important aspect of bitcoin may be the concept behind it. Bitcoin was created by developer Satoshi Nakamoto. Rather than trying to design a completely new payment method to over throw the way we all pay for things online, Satoshi saw certain problems with existing payment systems and wanted to address
them.
The concept of bitcoin is rather simple to explain: During the financial crisis of 2008, people from all over the world felt its
debilitating economic effects. And at the time of this writing (early 2016), many are still feeling the effects in terms of the dwindling value of their fiat currency (the currency approved by a country’s government). As the global financial system teetered on the brink of collapse, many central banks engaged in quantitative easing or in simple terms, turned on the printing presses. Central banks flooded the markets with liquidity and slashed interest rates to near zero in order to prevent a repeat of the Great Depression of
the 1930s. The effect of this was large‐scale fluctuations in fiat currencies and what has since been termed currency wars a race to competitively devalue so that an economy can become more viable simply by its goods and services being cheaper than those of its neighbors and global competitors. The response of central banks around the world was the same as it always has been when these things happen: Governments had to bail out affected banks and they printed extra money, which further devalued the existing money supply.
In bailing out the banks, there was a net transfer of debt to the public purse, thus adding to future taxpayer liabilities. This cre￾ated a sense of social injustice among some quarters. Aside from that, no one really knows what the long‐term effects of quantitative easing will be. Perhaps inflation at some point in the future
and a further devaluation of those fiat currencies who engaged in the schemes? What seemed clear is that central bankers, supposedly acting independent of governments, were taking many economies into the unknown and were prepared to devalue their fiat currencies at will just to keep the wheels turning. In doing so, they bailed out the very same institutions and bankers whose
reckless behavior had brought about this crisis in the first place.
The only other option would have been to let the whole system collapse and be purged, as for instance happened in Iceland. That country defaulted on its debt and endured great economic turmoil in the aftermath of that event.

Therein lies the genesis of bitcoin: a
decentralized financial system taken out of the hands of a few elite global decision‐makers.
When Satoshi Nakamoto came up with the idea of bitcoin, one key factor was destined to play a major role.
Decentralization means we are all part of the bitcoin ecosystem, and we all contribute to it in our own ways. Rather than relying on a government, bank, or middleman, bitcoin belongs to everyone, in a system called peer‐to‐peer, and we all make up the bitcoin network. Without individual users, there is no bitcoin. The more people embrace bitcoin, the better it works. Bitcoin needs an ever‐expanding community who actively use bitcoin as a payment method, either by buying goods and services with bitcoins or offering goods and services in exchange for bitcoins.
Due to the digital currency’s free market spirit, anyone in the world can set up their own business and accept bitcoin payments in a matter of minutes. Plus, existing business owners can offer bitcoin as an alternative payment method, with the potential to expand their customer base on a global scale. It’s easy to do your bitcoin and get involved.
