To be honest, I'm not this kind of guy who spend his time to expend about what he achieved. However: yes, I did advance Bitcoin.
Indeed, I spent hundreds of hours creating open-sourced talks and videos about everything I know about Bitcoin (https://youtube.com/playlist?list=PLVkpvudLgb2k-7dC2axeM_NBGgDLz7aKJ&feature=shared).
I spent dozens of hours writing flyers about why Bitcoin is a revolution and why it should be accepted in businesses (https://profedustream.substack.com/t/articles-and-flyers).
I spent hundreds of hours too talking to people about Bitcoin's security, Bitcoin's protocol, Lightning, and so on... during meet-ups I'm trying to develop as much as I can.
I do think that one day, someone will tell me:
"Hey man, who are you? I don't know you. What did you do in Bitcoin?"
The more important thing is that I will be able to say: "Even if I'm a pleb, I did everything I could to advance Bitcoin."
