Just took a little jump back to 2010 to look at what people were posting about. It kind of feels a bit sad now to jump back to the future and see every post about bitcoin as an investment. It would be nice to be in a time where people spoke and cared more about how to best progress the agenda rather than how to make a quick buck

Maybe after the inevitable big crash comes and the price stabilizes, who knows
What makes you think that a lot of those people weren't also in it for the money? I would think that probably only the very first few users who joined this forum we're in it exclusively for the tech and the vast majority of people who signed up after 2012 were mostly in it for the cash. You can also be a fan of the tech whilst hoping to make a bit of money from it like I was.
You're right about that, it's an entirely different community now because of the money that is there to be made, most of the guys who were here for the tech are probably relaxing on a beach somewhere by now. You can go to certain sections of the forum and find lots of good threads to discuss things, serious/technical discussion would be a good start.
Not necessarily. A lot of these people cashed out when bitcoin hit $1-100. Then even more at $1000. It's the ones that hodled and timed it right selling at the all time high that are probably on the beaches. I think the majority of posters now just dump their coins for cash as soon as they get it because for a lot of them it's seemingly paying their bills.
