I believe Bitcoin is the most disruptive innovation in computing since the internet and smartphones. This belief has motivated me to dive ever deeper into the Bitcoin space to understand the changes that it will bring to the world. I'm an executive-level software engineer that has created multiple products that are in worldwide use. My first contact with Bitcoin was in 2010 when I checked out its underlying software architecture — Bitcoinʼs price was around $0.10 then. Nevertheless, I really started focusing on Bitcoin only in 2017. Bitcoin had already reached $1900 at that time.
