Dogecoin (DOGE)

Its market cap of $13.4 billion is 30% lower than its 2021 peak, and it has lost 1.2% of value over the past week, trailing the broader market average that rose 2%. Despite sporadic support from Elon Musk, Dogecoin's utility deficit—lacking smart contracts or real-world settlement—leaves it vulnerable to faster competitors on this list like Figure Heloc.
