Dogecoin  was never  abandoned  in the first place, people  just undervalued  it. It's  not surprising  that most   exchanges  never delisted it over all these years,  considering all these years when the coin was seemingly  undervalued by most Crypto influencers. The recent  price hike was expected  when prominent  crypto enthusiasts  gave  Dogecoin  enormous  attention or hype as most people prefer to call it.
