While I start to do some research and try to wrap my head around what a witness actually is... I am starting to buy into everything everyone is saying about Tau on here. I still think I need to go back and try understand the fundamentals of blockchain before I start seriously getting into investing and understand exactly what the platform would provide for the world. In saying this though, I'd still like to know how I would do so and it seems like I cant buy any of the Agoras tokens anywhere? Where have they gone?
