for dogecoin maybe the upcoming bullrun still has room to pump again after elon musk dumps all the dogecoins in his hands and there will likely be big companies that look and want to buy dogecoin in large quantities in the future and pump even higher.
but for shiba and other meme coins there seems to be no place or no more opportunity to pump after the hype ended last year. because in the future there will always be new coin models that will take over the market just like the next bullrun.
