For me it seems like he is just using his influence to move the market, it is up to us if we want to move the way he wants.
We have experience a similar situation on DOGE when Elon Musk was pumping the price.
The wave could also be done by those new investors being controlled by FUD or FOMO.
I don't even think we have a choice than to dance to the influential tunes of Donald Trump at this moment. The truth is that Trump's influence is way stronger than that of Elon Musk on DOGE. As the president of the country with the strongest economy in the world, you should expect every statement Trump makes as regard to Bitcoin and cryptocurrency in general to have an instant impact.
Unfortunately you're right. There's no one to hold Trump accountable as he is at the top, and benefiting majority of the groups and people who sit in the upper class of America and other nations too. It's clear that there's manipulation happening, though I think the main thing to focus on is the long term. Getting caught up in the day to day never served anyone any good, even before Trump.
