The primary idea of Bitcoin is providing a platform based on the decentralized technology to send payments from one point to another without relying on the third party. If I am sending $1 Million to someone through the traditional payment system, I will find myself under the radar of the multiple investigation agencies even though I have submitted tax paid receipts and KYC details. That's happening in most of the countries, whereas in Bitcoin, no one would as you to show paperwork. If you have funds, you can do whatever you want 24*7 without relying on anyone else.
Bitcoin is the first implementation of a concept called "cryptocurrency", first described in 1998 by Wei Dai in the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control manufacture and transactions, instead of using centralized authority. The first Bitcoin specification and proof of concept were published in 2009 in a cryptographic mailing list by Satoshi Nakamoto. Satoshi left the project at the end of 2010 without telling much about him. Bitcoin community is growing rapidly as many developers are working on Bitcoin. Satoshi's anonymity often leads to false concerns, mostly related to a misunderstanding of the nature of open source-based Bitcoins. BItcoin protocols and software are publicly published and developers from around the world can review the code or create their own modified version of Bitcoin software. As with current developers, Satoshi's influence is limited to some of the changes he created and adopted by other developers, and he does not control Bitcoin. Thus, finding the identity of the inventor of Bitcoin is now just like finding the identity of the inventor of the newspaper.
