If only asking about memecoin I think it would be Dogecoin, because it is the source of everything, indeed without the hype about dogecoin from Elon Musk before then the memecoin would not have received the description it is now. In crypto, I didn't pay much attention to Dogecoin before but when the price was pushed up so fast it made me have to rummage through the places where I bought it in the past, there were indeed a lot of irregularities suspicious to me. But given the time to the present as well as the foresight into the future, I also wouldn't think memecoin will gain more positive beliefs, it's just a short-term and unsustainable movement.
