[Proposal] FOSDEM-like event for the Bitcoin community, by the community

Hello fellow Bitcoin hackers,

looking at ticket prices of upcoming conferences this year I got a little bit frustrated:

Bitcoin in the Beltway Washington: €294
Inside Bitcoins Hong Kong: €294
WIRED Money London: €1248
Bitcoin Finance 2014 Dublin: €599
Inside Bitcoins Conference & Expo Melbourne: €276
CoinSummit London: €677
Annual North American Bitcoin Conference Chicago: €202
Coin Congress San Francisco: €331
Cryptocon Sydney: €913
Cryptocon Singapore: €883
Inside Bitcoins Tel Aviv: €368
Bitcoin and Cryptocurrencies St. Petersburg: €37 (or donation)
Cryptolina Bitcoin Conference Raleigh: €202
Camp Bitcoin Black Rock City: ? (probably donation)
World Bitcoin Forum Bonn: €300
Bitcoinference Summer 2014 Amsterdam: ?
Bitcoin Central & Eastern European Conference Ljubljana: €300
Inside Bitcoins London: €495
Bitcoin Conference Kiev: €75
Bitcoin World at Money2020 Las Vegas: €2171 (yeah, baby!)
Dubai Bitcoin Conference: ?

With the notable exception of the St. Petersberg conference and the Burning Man camp the events are obviously not targeted at free software developers or mainstream users. So I propose to organise an event that is accessible to a broader audience, similar to the open source conference FOSDEM (https://fosdem.org/):

Free entrance / donation
Location at non-profit or academic venue
Possibility to volunteer
Free booths for free/libre open source projects
Lightning talks
Hackathon/dev rooms
Workshops for beginners
Possibility to trade/withdraw/spend cryptocurrency
Family-friendly
Colourful start-up fair
Friendly security staff (if any)

Let's make cryptocurrency conferences less about suits, but more about community and fun (hello shibes)! Ideas, comments, pointers to similar proposals welcome.

Cheers, Meinhard.

Edit: Added Coin Congress
