Maybe about 20% (which hopefully grows to millions in the future) of the coin could be set aside for dump protection. Once a whale tries to crash the price, the system automatically buys up most of the whales coins and reduce the effect of the dump to the barest minimum. If some bullish whales later buy some million pf dollars worth of that coins, the automated system directly sell about 20% of its holding to the whales and this is repeated to keep the market healthy.
No, this is what some foolish governments do to their fiat, its called (dirty) floating bands, and it doesn't work. You shouldn't fear the market, this is Bitcoin not some little altcoin, it cannot be crashed anymore, no matter how much and how hard you dump, others will flock to buy it at those cheap prices even faster, because bitcoin is that valuable to people (that even countries are putting their reserves into).
An Austrian economist would tell you: The best thing to do (regarding intervening), is do nothing. Let them do whatever they please. Its their lose and our gain. Don't fear the free market embrace it.
Oh, and such thing as "whale alerts" do exist, i have seen it in Telegram and some other social media (Twitter?). There are bots constantly monitoring the blockchain to give out those alerts.
As far as Bitcoin is concerned, whatever people are willing to give or not for it, none of its concern. The code has nothing to do with what arbitrary price the market assigns bitcoin. This is remarkable, and even more reason to make it valuable.
In fact, your suggestion would subtract value. Why would Bitcoin be tied to whatever non bitcoin thing there is? This is outside Bitcoin realm. Also think, just what is much, what is little? In the beginning 10k BTC bought two pizzas, that would be considered a whale movement today, you expect the code to distinguish between now and then, exactly how?
