Let me play devil's advocate for a second : most people don't have a single clue that cryptos exist and the mainstream media have given them such bad press being too volatile and associated with criminal transactions -we all know that the USD isn't, right ;) Moreover, I still find it quite difficult to buy cryptos online, even more to sell them for cash. I've just got my first STEEM rewards today and I still don't quite understand how to manage them and their meaning. I think a lot of us STEEM users are still a bit confused on that topic.
