as ridiculous as it sounds, most of retailer did exactly this like in the past bullrun cycle too, even the recent dips which caused bitcoin to touch $49k, there were so many retailers panicking and selling their coin at that price, which is kinda dumb in my honest opinion, if we're already going down so bad there's always bigger chance that the price could bounce back off and yet retailer doesn't seem to understand that.
this is why knowing basic of market could help massively in determining what step to take, the paper hand amateur trader will always be the one that become exit liquidity because they are just that bad. they should've stayed with DCA.
Indeed ridiculous because they are doing it wrong or they are doing it the opposite way according on what you described there. In each side that they choose to do, OG's will always have the chance to take advantage. They are only lucky because I believe that many OG's are still kind and they are already a long-timer in this market, so they won't do such thing as what @Algominer2 is saying there which is to exit liquidity.
Also, I don't think that a simple retailer that will enter can immediately pump up the market but there is a proper time for this and that will only be the time that the OG's will sell their possessions. When it comes to buying, I believe that many OG's now are into DCA method, so they don't usually wait for the dip and buy the coins of the retailers that panic sell when the market is in a bad shape.
Anyways, the crypto adoption is not yet full, so there will always be more people who will come late and usually they are only poor or so-called retailers but they can still learn later on and they will now become an OG too just like the most of us here and that will only be the time for them to revenge and also take advantage of those who are newly entrants in the market.
