Honestly, I don't see any interest in bitcoin or cryptocurrencies from Elon what he wants is just for his own gain and he saw that it is possible to manipulate the market to make a profit for himself and he succeeded once in the past when shilling bitcoin and doge. Regarding the acquisition of Twitter, I think he has a plan for his business, he is quite busy with tesla and his other companies, and I don't think he has enough time to buy Twitter just for crypto purposes. Don't overestimate him as a true crypto fan with just a few tweets from him.
What about the most of us? I think many of us don't also care about the cryptos but we only buy and hodl them for the sake of earning a profit. The real ones that care are the ones who use their coins for payment purposes only and they never made a complaint whatever the price ends up but what is only important for them is that they can send or receive money seamlessly without any restrictions. There's no need for Elon to buy twitter if all what he wants is to manipulate cryptos again because he already did it in the past but he buys it because he have a different plan. We are clueless for now but we will soon have a hint if what is it.
There are many possibilities about why Elon Musk would like to buy Twitter, one simple possibility is that he wants to influence politics on the US, most of those behind social media platforms are in favor of the Democratic Party and their policies, and even if Elon Musk does not want to interfere directly his approach to freedom of speech is more aligned with the ideas of the Republican party and could benefit them on upcoming elections, then it is likely this move has nothing to do with this market.
