Back then there weren’t any bitcoin meetups in our town Ljubljana and we weren’t sure if there will be lots of interest for it, but then again we were meeting anyway so there was not much to lose. We brainstormed on the format and decided that we will each do a presentation on something we’re interested in - and this is how Bitcoin Ljubljana was born. ...
