If your predictions are good, I'd be happy to get you $100 million in assets to manage. It's very unlikely that your predictions are good...
As you say you have expertise in the area, any chance I could ask you for advice or how to decide if its worth trying?
If you picked a HN comment at random, then the person who made that comment are overwhelmingly unlikely to raise $100MM at the drop of a hat. Picking a HN user at random won't do it either.
But there's not a lot of finance-related submissions on HN. The people in the comments may be unusual. And off the top of my head there certainly is an existence proof for at least a few investors on the news site for Y Combinator, a VC fund, such as pg or sama. There are obviously other VC people on here as well.
