These "projections" that Bitcoin will fall to 30.000 or so if Harris wins are, in my opinion, completely baseless and overestimating the US influence on Bitcoin.
Discuss & Disagree

There is a local forum that's very popular in my country and people often discuss things, like on Bitcointalk. Will you believe if I say that the government invests lots of money and creates bots to spread the misinformation? They even pay people to post good about the government. Of course, that's done unofficially but that's a very known fact among users. Don't you think that there won't be a similar situation on Bitcointalk too? Modern politicians understand the power of the virtual world, it's a great place to gain the attention of people with fewer expenses.
I believe that Trump will have bots all over the internet and some of them might be on this forum too. There is a chance for Trump to gain some % of votes by promoting the fact that Bitcoin will rise if Trump becomes the president. In some families, kids might push parents to vote for Trump for this reason, some Bitcoin enthusiasts will vote for him to gain profit on their investments and etc...
I personally believe that Bitcoin will rise with or without Trump and Harris. If they don't ban it and don't set sanctions, then Bitcoin will do everything well on its own.
