Elon Musk is no longer relevant in the Bitcoin community even if he goes on to say that spaceX would start accepting Bitcoin for whatever reason that wont don't change a thing.
Believe me, he is still very influential and can manipulate Bitcoin's price if he wants. The guy is one of the richest person, owns one of the most famous social media called Twitter (X). He has an influence, just imagine if he starts a crypto business and invests bunch of millions of billions of dollars into specific advertising, I bet he can change the fate of this coin for better or for worse but even without that, he can still manipulate it with his words.
Elon musk is a multimillionaire and I know for a fact that he does not care about the environment or whatsoever as long as it is beneficial to him. He has incorporated NFTs on his brand Tesla and we all know that NFTs are extremely harmful to the environment.
What gives you a reason to say that NFTs are extremely harmful to the environment? NFTs have nothing to do with environment, they are just harmful in a way that money is made out of thin air and too many dumb people lose money (debatable whether this last one is harmful or not).
