My pfp here on Twitter (and everywhere else) stems from back in the "early days" when I was mainly involved in the @Polkadot ecosystem. It's a ChaosDAO ape by @apeXchimpz that I have been using for years now (with no intent of ever selling). And since we're on it: my name "zerokn0wledge" stems from a deep interest for ZK tech, that I developed as I graduated from the Polkadot ecosystem into the broader space of modular blockchain infra. Kind of marked my "departure" from the DOT ecosystem, as my focus shifted elsewhere. Yet the pfp always remained, honouring my beginnings in this space. Also started to look back into the Polkadot universe a bit more again recently, and am actually positively surprised of all the cool stuff that is happening there. Yet, financially speaking, I probably made the right decision to expand my horizon far beyond the Polkadot eco back then.
