Could NOT understand your post Thus replying to the title: Did they died stinkingly rich? Why not ask Buffett, or Soros about trading?
Maybe these billionaires's decendants own technology in the future that could create a small artificial temporal anomaly where a simple 'B' or 'S' light signal would travel through faster than it's normal speed which Einstein concluded impossible The question is do they have a time-viewing device at present to slow down & receive those BS signals at normal light speed
