Why is it called a token? It is a cryptocurrency like bitcoin. In fact, since Bitcoin is set to become a reserve held by the powers, Dogecoin's features of low fees, inflation, and similarity of value of each unit with most fiat currencies position it to be the cryptocurrency of the people on the internet. There aren't many rivals.
If inflation (having unlimited supply) were a good thing, fiat wouldn't have been considered a shitcoin.
As for the fees, coins like Doge don't exactly have low fees. They are just cheap compared to bitcoin ($0.11 versus $60000) which is why when you convert the fee to dollar terms they appear cheap. Otherwise because Doge is also a copy of bitcoin, it means Doge has the same fee market as bitcoin and because of its other issues if it were to reach $60000 in a hypothetical scenario, its fee would be A LOT higher than bitcoin's.
What about those who convert their bitcoin to dogecoin to move it to other exchange and after it gets to the exchange they immediate trade to bitcoin back again. Let say Dr. A wanna send 2 BTC to Mr.B were the total cost of it would be around $10+ and they decided to convert to Dogecoin worth 2 BTC and move to other exchange, don't you think the wouldn't be that applicable?
