I believe it's just all manipulation and we are in the worst situation now compared to the last bull run, so expect a heavy correction after this. FOMO is happening, everyone is riding on the FOMO, that's a bad thing as the newbies will certainly learn the hard way.
But, with respect to dogecoins, I am not foreseeing Elon Musk to stop at any near future because they have already might have profited at least 10x of their initial investment allocated for dogecoin pumping alone; when they are already doing something with all profits then I guess they might keep continuing the same to get into a undisputable dominant position; I guess this is what exactly happening with dogecoin markets right now.
I agree that people are riding on FOMO right now but still considering the growth of bitcoin, we are still into initial phase of bull run which means we may see another multiple rounds of bull run in coming months hence FOMO may get more intensified in coming days. So, if FOMO continues then there will be no problems for naive investors for time being.
FOMO would only stop if big investors will start dumping, Elon is very smart, I don't see any possibility that he will just continue to hold, he needs to profit from what he is doing and the only way to profit is to dump. Based on the news I read, only few wallets are holding big number of supply, that means if one will dump, it will affect the market big time, and you know whales usually think the same, so expect a dump.
