Hello fellow Melbournites.. There's many a Bitcoin meetup in our hometown, just look here:
https://www.meetup.com/en-AU/topics/cryptocurrency/au/melbourne/also:
https://www.meetup.com/en-AU/BlockchainMelbourne/ is a pretty huge one..
I went to one once in 2013.. but haven't been to any networking groups since as I've only really started to take crypto seriously in the last 18months..
I'd be keen to check one out and see what goes on at these things these days.. Not much action in 2013 but I'd assume its different now.
