Quick Answer
Bitcoin, launched in 2009, is widely recognized as the first cryptocurrency. However, its creation was the culmination of decades of prior work by pioneers like Wei Dai (b-money), Nick Szabo (Bitgold), and David Chaum (DigiCash). These innovators laid the groundwork for decentralized digital currencies, with Bitcoin synthesizing their ideas into a functional system.
