Satoshi Nakamoto, but his identity is still unknown and I find it cool lol, if you're interested in the background of Bitcoin, well you should watch the movie "Banking on Bitcoin"
We all know here that the one created bitcoin is Satoshi Nakamoto, but we dont know about his identity not one of us but even if we cannot see his identity we are very thankful to him because bitcoin today is popular,indemand and most likely it is fast, stronger and bigger now.He brought opportunities to everybody to earn extra money to sustain tere needs and wants.
