it is possible and most likely Elon Musk will continue to promote other coins as well. But it's more likely that Musk will promote those coins which will put him in an advantageous position and care less about how that might impact the market.

So that's the main reason he doesn't promote any other coin unless it can show that it can add to his wealth. I'm not someone to say Musk is wrong; I'm just saying that's what I'm also going to do as an entrepreneur and try to increase my wealth as well. but why Elon Musk constantly writes about Dogecoin is not clear, most likely Elon Musk invests in Bitcoin and Dogecoin and therefore.

Elon Musk constantly advertises these two cryptocurrencies on his Twitter, and in general it doesn't matter for what reason Elon Musk wrote about these cryptocurrencies, the main thing is that after his message the growth of these two cryptocurrencies started, and this is the main thing.
