For Elon most of us know that his interest is mostly in DOGECOIN which is where he's got massive stake, he will not be pushing for bitcoin enough because he may not be having as much in Bitcoin and with DOGECOIN he may have some kind of control which he may not be having with Bitcoin, summarily there's still an intention he's got.
They're all pushing their different cryptocurrency because they have big stakes in them. They aren't pushing Bitcoin but Bitcoin is pushing itself and without Bitcoin moving other cryptocurrency aren't going to move. It's Bitcoin that controls the market but people like Elon musk doesn't want Bitcoin to increase instead they're projecting their favourite altcoins. There's politica around Bitcoin but Bitcoin has always been the one winning and not the altcoins. Bitcoin is that one cryptocurrency that no matter how bad you speak about it. It still won't go out of existence. Bitcoin always recover and that's one big strength of Bitcoin together with it being decentralized.
