HashrateIndex is a site focused completely on exposing data from the mining industry. Miners are notoriously guarded about their data since every edge they can maintain has significant implications. It's a unique product in our 21 Days of Data because it has such a specific focus.
Ethan Vera and Flip talked through each section of their site, why they picked the pieces of information they did, mining in North America and a little bit of gossip, too. It was a really fun interview to put together and its full of information you most likely haven't dug into yet.
