Mario fell down the bitcoin rabbit hole in 2016 while attending the Seoul Bitcoin Meetup, where he spent a year and a half self-studying, meetup organizing, and blocksize warring. He got his start working in the industry at Blockstream for several years before joining the Ledn team as Director of Community in 2021. In his spare time, Mario co-hosts the Unhashed Podcast, and enjoys figuring out how to communicate challenging technical concepts to the layperson.
