if big wallet owners sell all the Dogecoin they have I think the price will drop further. It was this anxiety that kept me from holding on to Dogecoin for long. I got into doge several times but as soon as I got the profit I immediately sold. Doge price has reached ATH lately because of the encouragement of elonmusk tweet. It would be terrible if at any time the price fell 90x the current price.
It doesn't require them to sell all the doge they have, it only requires one of the whale to sell 10% of their doge the market will already affected by it, many people actually keep watching their address and every movement matters.
I think it's crazy as well and allows market manipulation by these whales. The market could literally be brought down easily by them and even elon keep saying that the whales should sell their btc but none of them actually care. I think the whales gonna dump when the price is $1 and that alone already make them more than billionaire.
