The thing about meme coins is that their lifespan is either very short or very long, but when their lifespan is long (take DOGE as an example), they don't really keep going up all the time because their nature is that they only go up in price if they are hyped by the community and they get a lot of investments which obviously doesn't happen all the time and people only get excited and invest at their initial stages and as soon as they start crashing everyone sell and exit expect for a few who get stuck.

So, you can't really expect a meme coin to live very long if it's not getting any hype, and even if it manages to live long, don't expect it to magically hit another all-time high after the initial hype it might have gotten because meme coins don't have any organic growth just like other normal cryptocurrencies.
