Hello and welcome to steemit. I am not sure if the crypto people have their own little community or what, I do know there are a lot of them. Politics, if you like that then here is one tag #informationwar, Being as you were a fan of berniesanders, not sure what kind of reception you will receive but they are a rather political group. I myself stop by there on occasion to see what is going on Hive account@newsagg does a news gathering tpe post boths sides. ME I belong to a couple of groups, Hive account@newbieresteemday their tag #newbieresteemday, and Hive account@greetersguild tag #greetersguild. Both groups work to try and help newusers get a leg up, and to answers questions without fear of reprisal. So anyone from or using those tags are safe to ask questions of, If they don't know they will try and point you in the right direction.
