Does dlive have irc integration for its chat? Some of the chat bots have really cool features for user interaction and games for users to play, maybe they can be customized in the future for guessing games on prices and contests for the users, things of that nature to up user participation in chat. Sorry, haven't used wirecast so I don't know what it's capable of, but it sounds like you need something that pulls the price feed and just shows it in a larger text on your screen?

And finally, if you're going to be talking about crypto it's advisable to put prominent warnings and disclaimers on the stream for your viewers in case it ever becomes an issue in your country.
