I think the meme coin that can last a very long time in my opinion is Dogecoin, because only Dogecoin is able to attract investors and influential people like Elon Musk and other artists who have a lot of money so I believe that Elon Musk's support for Dogecoin is very capable to make Dogecoin last a very long time.
talking about elon musk support, i read this article:
Even Elon Musk can't save Dogecoin from crashing another 60%, analyst assertsit seems that the forecast is that dogecoin will drop 60% in the next few months and this time elon musk will not be able to prevent this huge price drop. the future will show us if this price forecast is wrong
