We didn't need to complicate the meaning of holder. We can simplify it by saying that those who hold Bitcoin on any platform, like an exchange or personal wallet, as long as it was their money spent, are called holders.
I don't think anyone here sells their coins right after they buy them. And they tend to hold, waiting for the right timing. Whatever they call themselves, short-term or long-term holders, it was just the same. So I think there is no need to argue about it because, for me, everyone who is here in crypto is considered a holder.
It's just that some think hodlers are only those that hold for long enough, some years or so, whereas others - they are traders or not worth considering.
