1. No one can stop bitcoin from increasing in price, it is only a matter of time for bitcoin to increase in price once it has accumulated long enough. Like previous bull cycles, bitcoin rose thousands of percent and where was Biden then, do you know?
Sam Bankman-Fried caused Bitcoin to drop in price by 60%. And he was just one guy, not connected to any government.
A few choice words by the US president, threatening to make Bitcoin illegal for US residents for instance, for do many times the damage SBF did. Bitcoin's price is based on millions of (mostly American) consumer investors buying Bitcoin. If that goes away, the price goes away.
2. It is inevitable that SBF will go to prison, because for what he has done, if he does not pay the price, the law in the United States will become a pile of trash for criminals. Similar to 2014, the CEO of Mt.gox was also arrested right after the exchange declared bankruptcy.
Yes, now you see why so many of us oppose Trump: because he frees criminals (including himself) who donate to his campaign, turning the US justice system into a "pile of trash" as you say. And yes, criminals like SBF being freed after they commit their crimes will encourage all kinds of criminals, and turn the purchase of Bitcoin into a suicidally risky activity for investors, which will send the
price of Bitcoin into the same pile of trash 
.
3. Bitcoin ETF is not new anymore, it was proposed many years ago, but this year the pressure came from large institutions Blackrock...Bitcoin ETF is not new anymore, it was proposed many years ago, but this year the pressure is coming from big institutions Blackrock...so approval is inevitable. If they don't pass it, I believe that when Trump is elected, it will happen even faster.
Nothing is "inevitable". Trump could do anything he wants, since he will be accountable to absolutely nobody.
And the ETF was already approved under president Biden and vice-president Harris. There's no such thing as Trump "approving it even harder".
The safe bet here, from the business standpoint, is to maintain stability in the market by voting for Harris, not disrupting the market with massive changes and corruption that Trump brings.
