Maybe Satoshi Nakamoto, who is the prime suspect for the creation of bitcoin under the previously thought pseudonym: Satoshi nakamoto, lol , but he denies his involvement, so no one really knows, but its probs him...
If you want to find out more about Satoshi Nakamoto, I recommend to check the article on https://cryptolinks.com/907/thecompletesatoshi. As this is a Wikipedia post, you will be provided with the detailed info. Hopefully, it will be helpful for you.
We don't know, it's a mystery. Quite an interesting one actually. But I don't bother much about who invented this cryptocurrency, I just make money using a cryptocurrency trading bot and I am totally satisfied with how things are going.
