BITCOIN (BTC) is a digital currency introduced as open source software by its developer Satoshi Nakamoto. Since it is open source, nobody owns it. Its most popular client is just maintained by a community of open-source developers. Bitcoin is controlled by all Bitcoin users around the world.
Using Bitcoin network is free , but there are fees only if you wanna hasten or speed up the processing of each transaction and it is voluntary.
According to a Journalist and TV host named Max Keiser, "Bitcoin is the cheapest way to move money around". But most of the people around the world don't know what Bitcoin really is. I honestly saw BTC signs many times before but I just focused about Bitcoin Earning last year when I learned it's rate went up too high that I was really astonished upon reading it.
