Lou,
What if it were someone that you DO know, and did have trust/faith in (knowing that $100k to them is not a big deal, and that your overall well being was in no way in jeopardy).
For instance, if your Great Uncle was a Multi-millionaire, and just wanted to get involved for the love of gambling... would you still avoid that game, or consider it?
Everyone would take the game if the "unknown backer" was actually known, trustworthy, safe, and rich enough not to be hurt by a loss. There are no downsides left.
