On January 3rd 2009, Satoshi Nakamoto created the Bitcoin network as a form of cryptocurrency. It was the first time in the history of money that someone was introduced a form of money that is absolutely intangible, does not exist in a any physical form; which means that it was introduced as a form of money can be used as a means of exchange yet can not be touched or physically felt.

More importantly, Bitcoin was introduced as a form of money that is completely decentralized. Bitcoin network was introduced as a system of money that totally forbids any form of control by governmental or private institutions including the brain or brains behind it's existence. Bitcoin was created to run on a digital ledger called the  blockchain technology.

This system of money was completely new to human existence when it was first introduced as there's never been a similar system of money that was ever adopted as a means of exchange and that was why many people who got the knowledge of Bitcoin at it's early stage of existence never believed that it was going to be a successful project. It was because of the numerous uncertainties surrounding the possibility of the digital coin to succeed that made many people who got the first hand information about Bitcoin to  neglect it even when it would've cost them very little or no money to own hundreds and thousands of bitcoins then.

Despite the doubt by majority of the people who were introduced to Bitcoin as it's earliest stage about the possibility of the coin to achieve the projected purposes it was created for, Bitcoin went on to defile all odds and successfully become first cryptocurrency project that was approved as a means of exchange and store of value in global market.

Today, Bitcoin is currently used as a means of exchange many countries and provinces of the world and just 15 years after Bitcoin was launched, a piece of Bitcoin is currently a little above 65,000 US dollars. The people who never believed that it'll become a successful project hence failed to invest in it when it was first introduced are now living a life of deep regret.

Bitcoin today is considered as the future global currency because of it's ability to solve global financial problems like allowing people from different parts of the world to transmit money at will, anywhere in the world and at any given time. Bitcoin is no longer solving the financial problems of 50-80 million people in one particular country instead, it's now solving the problems of more than 7 billion people and that's why Bitcoin network will continue to expand across the globe until it finally becomes a legal system of money in all parts of the world.

Considering the rate at which Bitcoin is spreading across the globe, it might be globally accepted as a means of exchange in all parts of the world in 10 years to come.
