Of course, no question! Evidences lead to Satoshi only exist in relation to Bitcoin.
But honestly, such a person will not disappear into a lonely cave somewhere, smoke a cigar and think:
Hopefully nobody will find me!
Yey, it is possible for me, that he might be have supported other projects under another pseudonym, or maybe even still does...
It's just a hypothetical question that I have asked myself here. I am of course fully aware of that Satoshi would be pretty stupid if he could be connected to other projects without a doubt.
I hope from heart that will never happen, that he will be exposed, but he not want it by himself.
What I want to say with this: It is completely human to think about such a myth and the person behind it...
It has little to do with evidence, that is rather irrelevant for me here...
