I also believe that majority of these Memecoins that have made it to the top gainer spot, owes it to exchanges like Bitget that listed them which eventually caught the eyes of investors.
That's one way to caught the attention of investors but that's not all because it is created based on Dogecoin which is a memecoin. If dogecoin didn't become popular the other memecoins would also be the same. For altcoins, it is also depends on its uses and its potential in crypto community. Memecoins right now decreased 12% and if you compare it to altcoins which is at 5-7%.
