Does a bit bother a horse?

Excuse me, but could you please elaborate on the phrase "Does a bit bother a horse?" I'm intrigued by the seemingly unconventional juxtaposition of a digital currency term "bit" with a large, four-legged animal like a horse. Are you perhaps making a metaphorical comparison, or is there a specific context in which this question arises? If so, I'd be fascinated to hear more about it, especially since the typical associations with "bits" in the world of cryptocurrency relate to fractions of digital currencies, not equine well-being. Could you clarify your intent and provide some additional insight?
