I don't think there will be some new memecoins in the future that will last longer in the market, because they are not pumping the way people want to be seeing them pumping in the market. Many people have experienced a lot of disappointment from some new launched memecoins that will make them not to invest on any new memecoin for long years, because they are not reliable like other coins that is still doing well up to date. 

Looking at some new memecoin that is standing since they are launched, I don't think they will maintain a positive results before the memecoin will fail investors, because they don't have solid teams that will make investors to remain in that investment for long.
