One more discussion about this is never too much I guess!
The real story of Satoshi Nakamoto is still a mystery no one knows who the real inventor either Satoshi or Haal Finney but there is always the controversy that Finney is Satoshi Nakamoto but he refuses to do it. In an interview when an anchor asked if he was the real inventor in response he replied that he was not the inventor and refused the claim. Before he (Finney)died in 2014 he said that he never met satoshi instead he met him online and the picture shown is fake if the picture of Satoshi is publicly available then how he is still anonymous.https://blog.lopp.net/hal-finney-was-not-satoshi-nakamoto/
