I saw a coinbase screenshot last night of a fill at over 100k. I'm not quite sure how prices are reported though; it was an autofill for a $50 order, so I assume a market price, and that it was filled over 100k would have been due to coinbase's spread. I'd still sort of think that would be reported though, but if not, is it perhaps only limit orders that would count? I sort of assume coinbase sets their bid and ask as a spread around the last market price, so allowing a market order filled at their asking price to push that upward as long as they're the only activity would be...problematic. So it's not impossible that's what's happening. And given the fill at 100,112 or so, it'd imply that with a 1% spread (theirs may be higher these days) the price they were spreading around would have been more like 99,600ish.
Obviously could have just been a fake screenshot but it didn't give those sorts of vibes.
