Stefan Thomas' connection to Bitcoin is notably marked by his creation of the "We Use Coins" video, which played a significant role in popularizing Bitcoin and educating the public about its use and potential. This video became one of the earliest and most viewed explanations of Bitcoin, contributing significantly to the initial spread of information about the cryptocurrency. While Thomas later became more closely associated with Ripple, his early efforts in promoting Bitcoin awareness have had a lasting impact on the cryptocurrency's early adoption and public perception.
