That is the $44 Billion Dollar Question.
Which is roughly the current market cap of Bitcoin as I type.
If you asked this question among a group of cryptocurrency enthusiasts, they will all likely look at you and say,
"Satoshi Nakamoto created Bitcoin, duh."
But, who the heck is Satoshi Nakamoto
What we know
Satoshi Nakamoto is an anonymous individual (or group of individuals) that invented Bitcoin. He released an extremely technical white paper in late 2008 called "Bitcoin: A Peer to Peer Electronic Cash System".
Nakamoto mined the very first bitcoins and accumulated over a million coins in it's beginning stages. It is estimated that Nakamoto owns at least 7% of all bitcoins ever to be created. No new Bitcoins will be created after it's supply reaches 21 million coins.
Satoshi Nakamoto isn't really a person at all.
In my opinion if Nakamoto really was some individual he would have come forward by now. That or someone would have figured out his true identity by now.
He hasn't, and they haven't.
Plus, the technology behind Bitcoin is truly masterful and is an engineering marvel. We are supposed to believe this was all cooked up in somebody's basement?
That seems like a stretch to me.
Especially when you consider this this..
