the only reason why bitcoin price dropped during the worldwide panic was that the bull market hadn't started yet and price was stuck behind a rather strong resistance and couldn't break it. so the tendency to drop was already there and whales took advantage along side the panic sell.

if another similar crash happens during the bull market it won't affect bitcoin at all. it will just lead to some whales losing a huge amount of money trying to go against the market just like what happened during 2017 and bankrupt many whales.

you have no way of knowing that. just because some shitty site shows a movement and calls that a "whale" it doesn't mean it is real. that is $190 million you are talking about and i don't know any bank that allows you to transfer that much money to a bitcoin exchange to buy bitcoin with it! they will shut down your account in a blinking of an eye if you try to do so.
