another bizarre fact if in seeking well one can find a patent file in the name of Satoshi Nakamoto which dates from the years 70-80 , this project has been carefully prepared well before 2009. And just my opinion and hypothese I think bitcoin is created by several experts in different fields, even in biology and music, but that team of expert probably did not know the finality of project , if you cut one project in several pieces the person will not know of finality of project because is limited with only by the task that is asked and for finish that is a rich person i think he create bitcoin no for just decentralized just for not pay high dollar for bank just for create his own bank is moving his fortune on the bitcoin step per step
