Listing of a big cryptocurrency exchange is a very good way of promotion.
Meme coin needs to have a good liquidity and listing on a big exchange will help to increase this liquidity.
I think that a biggest part of costs meme coins spend for listing on exchanges and promotion.
Without promotion it is impossible to pay attention to meme coins. And some times promotion is very expencive.
And if the team has no enough funds, then that's the problem. This is why most meme coins can't make it in the market because it is just created for the mere fact of pocketing money from naive users. And if they can't attract traders, they can easily be shelved. I hope this one is not waiting for a miracle that one day, Elon will promote their meme token for possible pump of their price...
