I saw you in an ongoing thread about blockchains event
I can't really think of a reason you had to create another
Different people already gave their views in the thread that covers most of your question in the questionnaire
And you know, I have analyzed these events, but there is one question left.
if you had analysed and done your research you should have seen the type of people that attends( investor's, developer's, enthusiasts etc)
Well personally never been
Not something have seen or been held in my country am aware of
Currently not interested since I see no benefit for me
Except from knowledge which I can just ask here
