🟠 Bitshala Meetup in Surat | Decoding Bitcoin Our first meetup in Surat was a meaningful conversation around one question: What problem was Bitcoin created to solve? To understand any solution, one must first understand the problem it was created to solve. We explored the history of money and the monetary problems Bitcoin emerged in response to, helping participants understand why Bitcoin is fundamentally different from just another asset. A few wanted to go deeper, so we happily recommended The Bitcoin Standard by @saifedean and Broken Money by @LynAldenContact as starting points. Thank you, Surat. We’re just getting started. 🟠
