$SAND as well $MANA and more than 10000+ other assets, $BTC included are suffering under 1 major manipulator since 2017! Their pattern is always the same, first selling altmarket trading bags, then BTC and repeat. And this all to trigger stop losses, liquidations, panic etc and then waiting, watching, collecting money and starts accumulating cheap assets. They already were awarded with 4b penalty, next time should be 4t, because its forbidden behaviour in every jurisdiction and other exchanges are earning enough through fees, there shouldnt be any exceptions!
Learn about this major manipulator and their draining session patterns! They are always simultaenously buying and selling but with different wallets ofc! Synchronized drops, crashes, flash crashes etc are always started by this major exchange!
