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
But if you look at the concentration of the overall DOGE distribution in the top wallets, you don't know who controls those and whether the DOGE are even brought to market ever. If not, a 60% price crash looks more dramatic than it actually is.
