Meet The Team

James Preston

Executive Editor

James is a writer and media commentator who has been reporting on how the Tech industry will make the world a better place for 14 years, with a large following on South African radio. He is an early adopter of Bitcoin, and began reporting on its revolutionary capabilities in late 2014.

Philosophical by nature, he is intrigued by how the world works, and in turn, how it can be bettered. James believes wholeheartedly that the world can become as close to perfect as we humans can imagine, but it will take a lot of effort (and time) to get there. He believes his life purpose is to inspire people to believe this, and find their place in helping humanity achieve it.

James regularly does talks on emerging technology and its impact on society at Universities, global conferences, and events. To invite him to speak at your event, or comment for your media outlet, email

Shaun Ritson


Shaun has been working in IT since he can remember. DJing for school parties and helping friends with their computers were his speciality. He took this skill into the business world, where he built a very successful IT operations career.

He joined Derivco in the late 2000s, where he continued to make his mark in IT infrastructure. It was here that he began to hear about Bitcoin and cryptoassets, and started the "genesis WhatsApp group".

The original "SA Crypto" WhatsApp group is where it all began, and his careful facilitation and hard work grew it into South Africa's largest blockchain community. In 2017, he co-founded Avantcore, a blockchain R&D firm, where he and his partners are building some of the most exciting blockchain tech in the country.

He remains passionately involved with Global Crypto, and supports the team on an ongoing basis.
