They dump some ETH and BTC. Then the trend looks down, traders then sell.
The big guys are holding BTC in the 60,000 area
ETH was bought continuously in the 3250-3300 area
They dump, then buy cheap, because they know there will be an ETF,
so they want to buy at the bottom, they sell then buy.
Logically, they sell 1000, buy 10,000
