Musk obviously has the talent to have created bitcoin and it would make sense that he wanted to remain anonymous. Maybe he had a "no compete" agreement with PayPal. Who knows. I know this is speculative, but it's interesting to think about. If he is the creator of bitcoin and he does have 1 million bitcoin and bitcoin goes to $1,000,000 that would be $1,000,000,000,000 (1$ trillion). That would be enough to fund a Mars Colony!
