I don't think we need to find out who the guy behind bitcoin is really. It is better off people don't know who satoshi is so he doesn't get prosecuted by federal authorities. If we had a bitcoin leader, it would really contradict the open nature of the technology.
Satoshi is anon developer who abandoned his project just like all the other devs who make pump and dumps.
Bitcoin is the biggest pump and dump in the history of PnDs,
bitcoin is nothing compared to stock pump and dumps. beside that, bitcoin is still here while not many expected that at the very beginning of bitcoin. satoshi most likely left as his side of the job was finished.
