Weird because of the odds that's being placed for Kamala? Well, that's what the bookies are all about for what they think is weird for us might not be for them.
I don't mind if Trump will mention Bitcoin or not because they're all just words and marketing campaign before the US citizens that are into Bitcoin. It moves emotion to make them believe it is.
Whoever wins the debate will get more votes afterwards if something is interesting about them. But I think what people wants to hear is about prioritizing US citizens and world peace.
I think it's not because of the odds but it is just their verbal expression. Even what the OP said can imply that Harris likes to say the 'weird' word. If about the odds and the bookies, I think there is no weird on them but there is always a reason about the odds that we can see on our screens.
I think a lot of us are now aware about the involvement of Trump in Bitcoin, so yeah that it may not really matter if he will still mention the word BTC or not. Though, him mentioning it, can only give more positive impression to the coin. That shows that they are not just a simple word. And as you said, they can also act as a marketing campaign or a material for it. They are known for these words, so we can say that it was super effective.
However, I think before Trump got involved in BTC and often use this word, he must have another word. Not just word but I think he also have a hand gesture and a facial expression. You mentioned emotion there but they can also use it if their goal is to attract people (lots of them).
There might only be people who was like not having an emotion and they won't ever fall for these. Winning a debate seems impressive but people can still have a favouritism, so they might still stick with their favourites, no matter what.
