In fact, memcoin is no different from ordinary bitcoins, altcoins and all other cryptocurrency assets, just for some of them we came up with memcoin, but this does not change the essence. And as we see, you can sometimes even earn more on memcoins than on ordinary bitcoins or altcoins
It is their defense, and the only thing they actually have as an advantage (some of them!) is that meme coins can target a specific audience.
Doege made it a hit by raiding on a 4chan meme, it was rapidly adopted by the community and it had a fan userbase, a normal coin with no specific name can't do this, so if you manage to get a coin with a cool name, targeted at a specific group, be it fans of a show, of a film, of a game or something like that and offer them a true opportunity to actually use the coin for fun you can achieve more than established coins.
The actual problem with current meme coins is that they simply print them by the hundred without caring, thinking that the community will build around it, which is close to impossible!
