I think i support your reply, 2030 is just 5 years from now and so far those listed Memecoins are doing pretty cool compared to the rest moreover they're not Bitcoin so we never can tell what might happen on the long run although they've shown that they've got good potential but it's not in our power to decide what they'll be like in the future we can only keep our fingers crossed and buy them when we feel and sure it's the right time to profit from them, you can add DOGE to what you're holding mate, it's doing pretty well and won't regret it in this bull run.
Even in 5 years, memecoins will not do that great. Existing is different than doing great, yes they will exist, but far lower marketcap than what we have right now. It is not going to be that great, we are going to end up with a better result with time, so we should not be expecting it to do that great.
Obviously this is going to be something that will take some time, but because this is not the greatest point right now, we should not be expecting it to be great. So being outside of top 100, is still "existing" technically, and half of it will be outside of it. Maybe doge can still do fine, because no matter what happens, doge still survives, so maybe that can survive, but I expect no other memecoin to exist at all.
