They would just want to clear the stance so that nothing comes as a surprise when they disclose later how much they might have purchased during this fall and holds huge qty of btc for themselves and also might purchased in their portfolios as well. Many such institution now would be buying with the fallen price and looks good too at this rate.
I, too, think that this is what's going to happen. They are just waiting for the "right" price, for the lowest one. But who knows the new bottom for Bitcoin? Nobody. Wait to long and you'll miss the bottom.
Now people from Goldman Sachs are "predicting" Ethereum to eclipse Bitcoin in the future, but we don't know if it's a strategic move to lower the BTC price even more before buying.
