My guess for the downvoting is some mixture of these reasons or others:
* This posting isn't the place for your comment--try an "Ask HN: evaluate my idea" or something.
* Your point "I need $100k for my idea, I can't see why this is necessary nor why anyone would give it to me nor what I'd do with it all anyway" took too long to get to and you probably would have gotten some responses if that was all you had.
* Perceived money-grubbing. "Are you a sociopath?"
* Perceived reasons why your idea Won't Work
* Complaining about being downvoted
* Your comment is structurally similar to some spam comments I've seen--greetings, link(s), bullet points, ALL CAPS at places, already downvoted. Instinctive downvoting.
