That's a good term for my experience...inside the crypto circle. Yes, I've heard of alt coin as well and etherium (SP?). I've even made a bitcoin purchase or 2! It's intimidating but not that hard. Steemit is more crypto experiential because there is something to do on the platform - read and write content. Whereas Bitcoin you just jump through hoops to acquire it, hold onto it as you try to find somewhere that accepts it.
