For me, there's only one memecoin and that is Dogecoin. The other memecoins are only copy of Dogecoin ot created based on Dogecoin. It's not really that important in my opinion but it did help bring more people on the market which is good enough. Memecoin is created for fun but because many people are using it then that's when the memecoin is more than just a coin for fun (Dogecoin). Other people are buying memecoin because of the hype of the memecoin but when the hype is down then the discussions are dying or the discussions about the hype memecoin are becoming less and less.
