Bitcoin is not the first digital currency and that people can have the knowledge about digital currency and then copied it created bitcoin that got its popularity up to present.

The guy that was mention OP as I read the article were not convincing in my part and the last part of the article might just be created or something to add or point that he is the one created bitcoin. If that guy had been prison in jail how would he create such design to make mining bitcoin faster? Besides, why would he ask the Judge where he can ask from his friends that can visit or call by him anytime? And why he would continue to do bitcoin when he can't enjoy it anymore. Why don't he accept it that he is satoshi so at least even in jail he could have his name be known through his creation?

In my own opinin bitcoin is created by a group of people and to protect the names of the members of the group they had to keep in silent that may even include the guy as part of those who created bitcoin.
