Trump, a convicted criminal and somebody who has been found guilty of running multiple scams all of his life, will have his own business that competes with Bitcoin and/or the crypto industry, and he will have the full power of the US government to give his own company unfair advantages over competitors. And Trump has demonstrated, over and over again, that he will absolutely use the US presidency to enrich himself at he expense of the American people.
that's basically just your personal opinion, and it hasn't been proven true that what you said will be like that. and from what you said, it seems like you don't really understand us politics, because even though trump can become president, he can't use his power to control the government to support his business, if he really does that then his political opponents will use it as a weapon to attack him and remove him from his position as president. so there's no need to think too negatively about what he does.
