IMO Elon Musk already lost his credibility by tweeting again and again for DOGE and now nobody caring for it. I would like to say he is now more like McCaffee because DOGE has no future nor a use case in real life instead of pump and dump and make people to loss his money there.
I would like to add another point here, Elon love trolling and make fun of certain situations, now as he saw crypto market is flourishing he used his twitter handle to mess with the people heads and seems like he was successful in this regard. But by tweeting a lot about Doge he surely lost his credibility.
