Technically, 1 bit equals 100 sats. I think the confusion comes from ‘bits’ already being a familiar unit in computer science, tied to any digital process. So using it in Bitcoin just adds another layer of ambiguity.
From a tech perspective I agree. But the whole ‘can I just buy a bit of bitcoin?’ question seems essential for mainstream adoption. So ‘bits’ can intuitively be understood as a bit of bitcoin. Whereas ‘sats’ need explanation. Don’t get me wrong, I love sats. It’s our culture. But purely judging from a marketing perspective, bits makes more sense imo.
