Probably those who said that Bitcoin will fall to $30,000 are those anti-Bitcoin or at least the ones who are following Peter Schiff all the way.
Bitcoin will fall to $30,000... only after the bull market. It will only touch that price when we enter the bear market.

Those are completely baseless prediction and Bitcoin will be fine like what the OP said. I mean Biden, who is against cryptocurrency didn't have that much effect towards the price, and adoption of Bitcoin. In fact, we've seen ETF's being approved during his administration. As for Trump or Harris, Bitcoin don't need the two of them as much as the two of them needs Bitcoin in order for them to win in the presidential election. Bitcoin will be just fine no matter who wins in the election. The US might be a superpower, but they have little effect when it comes to Bitcoin and it's price.

Bitcoin will thrive like it always be.
