Personally for me, the most "Bitcoin-ish" things I have ever done is spending 27 days, 11 hours and 23 minutes minus AFK time on Bitcointalk to obtain the rank Legendary. With the hope that one day I will be able to put it inside my resume - alright, just kidding.
What's the most Bitcoin-ish things you have ever done?
eg. laszlo for being the first person to buy pizza with Bitcoin
I will say that I am yet to do it. I am planning to make a YouTube channel where I will share the experiences of other people in my country related to bitcoins. There is still a lot of growth opportunity for bitcoins in my country and thus there is opportunity for such channel as well. Current channels in my local language are mainly focused on promoting new exchanges with shady practices.
