Dogecoin is the first meme coin.
Shiba Inu is copycat from Dogecoin.
Floki, Babydogecoin, and Mona are copycat from Shiba Inu.
Pepe is first shitcoin run in BRC-20 chain.
You're forget with Bone ShibaSwap, Dogelon Mars, Doge Killer, and Dejitaru Tsuka where all of them are shitcoins.
If you want to buy meme coin, you should only choose in Dogecoin.
You forgot to mention Garlicoin, and Monacoin (not to be confused with the copycat "Mona"). The first one is relatively new to crypto land with a limited supply of only 69 million units. It's completely different from the average "meme" coin. But it has a low price due to poor marketing/promotion efforts, and inactive development. Then we have Monacoin which is a very old "meme" coin often admired in Japan. This last one has survived, despite the fact that other "meme" coins have taken the crypto world by storm.
While investing in "meme" coins is a gamble, it wouldn't hurt doing DCA for short-term profits. For something more serious, Bitcoin is the only solution. One thing is certain, and that is no other "meme" coin can outmatch Dogecoin in terms of market cap and price. It's like saying Ethereum or Solana will overcome Bitcoin in the future (which will never happen).
