Leaving out stablecoins, then the token with the largest marketcap is Shiba Inu. Knowing absolutely nothing about this token, I decided to read the text about it on Coinmarketcap:
Once upon a time, there was a very special dog. That dog was a Shiba Inu, and this dog inspired millions of people around the world to invest money into tokens with the dog's image on it.
Yeah, I don't want my global peer to peer currency, which is securing and transferring billions of dollars worth of value every day for people around the world, encumbered with this sort of trash, thanks.
...
Over 100 clones of a completely pointless memecoin. I'm more than happy for Ethereum to bog down their whole project by catering to this sort of nonsense.
Tell me what problem Shiba Inu is addressing? What question can be asked in which Shiba Inu is a solution (other than how do we part fools from their money)?
In general, all derivatives of Dogecoin as well as anything that runs on their chain is useless for all practical purposes. It's full of greedy vultures who want to make a profit of $10 or $100* shorting their preferred DOGE shitcoin.
*I call them foolish greedy people aka. cheapstakes, instead of intelligent greedy people.
