I don't know anything about coinbase, but you're taking the least-generous possible interpretation of this. A really simple re-statement is that your bearing has consequences for other people, and if you're having a shit day and feeling miserable, you can either conduct yourself in a manner that poisons everyone around you, or you can try to keep yourself together. "Positive energy" is, I'm guessing, one way to get at this idea, though it's not how I would frame it myself.

As an aside: I assume that you know this from your own life, and appreciate when people behave in a manner that cares for the emotional commons of wherever you are. Is your objection to it here the fact that it's a giant stupid company ostensibly trying to curate your feelings, and that's annoying and (probably) hypocritical? Or do you really object to the premise?
