I noticed the signature campaign on Donald Trump but I missed the later one on Kamala Harris but by this fact that mindrust runs two campaigns for two Presidential nominees, it's fair enough and he did not skew to any nominee between these two ones.
Did you read the thread for the Kamala Harris thread?
I read the thread, and I think it is probably consistent with Harris. I do agree that there does seem to be a conflict of interest for one person to be running competing political signature campaigns, but I don't think there is any rule against it. It is also very well possible that Harris simply decided to copy Trump's strategy of advertising on the forum, and didn't bother to change even any of the minor details.
These things have nothing to do with cryptocurrencies or Bitcoin. The fact that someone said a word or two about it (exclusively for personal benefit) does not mean that everyone should be obsessed with it.
Trump has made bitcoin regulation a campaign issue. He wants less of it, and also wants to provide market incentives for more of the crypto industry to move to the US. So the outcome of the election is inherently relevant to bitcoin.
