Interests

Apart from blockchain development and crypto, I have been traveling a lot around the world, from playing poker in Vegas, diving in Thailand, skydiving in New Zealand, climbing over 6,000 m in Ladakh in Northern India, and going over the polar circle in Norway. I eventually settled in Thailand's countryside, where I enjoy a quiet life with my wife and kids.

Here is my website relating most of my adventures: https://www.voyageboost.com

Most of my time is now spent following and contributing to the crypto world as I believe that it will be a game changer in many areas in the coming years.
