It will not make much of the difference, there are not so many Bitcoiners and I expect most to just not go voting.
But it's quite an advertising for both Gemini and the-new-Trump-that-supports-crypto. And I fear Gemini may have been scammed in this business, since politicians well... lie a lot, to say it simply. And the POTUS is not the whole government, he can't do too much (which can be good or bad, depends...)
