This is where Groww Digest comes in. For the past eight years, every Sunday, Groww Digest has brought finance and investing to life through engaging, real-world stories, such as the one about pessimists versus optimists: Was Lord Kelvin right all along, or did the Wright brothers prove him wrong? Or the story from 1984 about good versus bad: When a polite bank robber made the world question, "Does charm excuse a crime?" Or when even experts failed to see the truth when a couple sold a $3.6 million fake painting.
