True Bitcoin users care about privacy and anonymity so Instagram will not be their favorite platform to discuss about Bitcoin. Who need Instagram to show a face and expose their identity to the crowd?
Twitter is better than Instagram or Facebook for cryptocurrency communities but I know scammers are abundant on Twitter too.
For technical discussions, developments and helps, they can get it on Bitcointalk.
True. But what are they going to post on Instagram about wealth+bitcoin anyway? A picture of their hardware wallet? A screenshot of their wallet app balance? It doesn't make much sense. The only photo I could think of that someone might post are photos in a Bitcoin conference/meetup, and that's pretty much it.
