I won't recommend investing in unknown meme coins at the moment. We know how long it took for another meme coin to gain some relevance after dogecoin so this two will dominate for sometimes before another memecoin get a chance. Even the well known memecoin won't gain some volume until the bear market is finished and other projects are begining to gain some price value. Memecoin are just speculation coins and investors only turn to them after they have made some profits from their other altcoins or Bitcoin.
90% of the existing meme coins won't make it past this bear market as they'll die due to lack of trading volume. There isn't enough money circulating the market as in the time of the bullrun which result to people putting money in any rubbish project and still made profit, now putting money in those projects gives nothing in return instead you lose all your money.
