If price doesn't drop below 9500, then it might just be some big trader trying to move the market. In that case, assuming he is shorting (and not selling), if we do see price move back above 9750/800 (don''t know how much losses they can take), to see those market sells turn into buys. Thing is, volume on Binance was big as well, so not just a Bitmex whale i think.
I do remember from the 2019 rally, also many big sells, but eventually price pumped quite big from the 9K to 14K. So first one i didnt want to say anything, not the first time, but now, just wanted to mention it. Think we have a range now, 9800/750 and think 9600 is a level as well now.
