There was no large-scale external transfer into exchanges on the blockchain; the sell-off originated from within the exchanges themselves. The biggest selling pressure on weekdays was from BlackRock ETF redemptions, which stopped after Friday's close. However, on Saturday, BSC-related exchanges actually experienced the most severe crashes (e.g., Aster saw approximately -25% in a single day). This indicates that the weekend selling pressure was primarily driven by internal exchange activity and leveraged liquidations, and was unrelated to traditional institutional channels. As for what actually happened, you can figure it out yourselves.
