If someone would have an idea how to get value out of $100K in AWS credits, would you think they would tell you? Why wouldn't they take the idea, pitch it, get $100K in AWS credits and then double it themselves?
Because he's not asking for ways of generating more than $100k profit out of his $100k AWS credits which would be quite difficult. He's in the unique situation of having $100k in free AWS credits and would probably be happy getting back half that as cash.
