Validator Spotlight - UNL Deep Dive - Brex.io

TL;DR: These companies and individuals included on the rUNL are the backbone of a 20bil dollar financial network. These posts dive deeper into a company's background, financial backers, integral partners, and other features to better understand who each of these validators are.

Bitcoin Black Friday is back, for another year. November 24th 2017

2017 has been an interesting year for me. I started working with bitFlyer, a Tokyo-based Bitcoin exchange, on their US expansion. I've been thrown deep into the world of trading and it has deeply changed my perspective of how I view Bitcoin is valued.
