Hello friend @crypto.piotr.

That's one of the big possibilities, the BTC market recovered quickly and the volume really increased, it's very likely the theory of some whales looking for a market crash and capitalize more BTC in their wallets.

I don't think the market will fall further, or not for now, as it had strength to hold up.

Good point you make about AltCoins, which had no negative impact of great magnitude due to this small drop.
