There are some people who have claimed themselves as satoshi nakamoto. Craig is one of them. I'm sure all of them are fraud. Just trying to get into the focus, they are nothing but attention seeker. Anyway, can someone give me a complete list of people who have claimed them as satoshi nakamoto?
I do not surprise by that news because with the popularity of bitcoin now, many people want to be the founder of bitcoin but they can not identify if they are the real Satoshi Nakamoto. They do not have access to Satoshi's wallet and they will say that the private keys were lost a long time ago and try to convince the public that they are telling the truth. I do not think much about people who claimed them as Satoshi Nakamoto because they are not the real Satoshi Nakamoto as long as they can not access the wallet. But well, we will see many more will claim themselves as Satoshi 
Why did he choose to remain anonymous? Why didn't he want the credit? Maybe there many reasons behind this. People believe this was commended to be the reason for bitcoin's success too but his fans have been curious too. Fakers gonna fake but the world is pore to about him or her.
But to be Honest? I am afraid if Satoshi or the group behind Satoshi is still alive as the hunt from the authority or the groups is rampant yet no proof of personality .
