Wow, I had read about the new VP but did not know this aspect. It seems then that Trump's pro-Bitcoin turn is in earnest. In general I don't trust politicians, and if it's on the campaign trail even less but Trump would be neither the first nor will he be the last to change his stance on Bitcoin (remember Saylor, for example). He also received $2 from the Winklevoss twins. But if the VP has personally Bitcoin it seems clear that if he wins with his policies he is going to be favorable to Bitcoin and all that surrounds it. There are also several big name Republicans involved in Bitcoin and the Mining Industry, like Ted Cruz for example.
Thank you, OP for pointing out this fact about the vice president nominee JD Vance. With this choice, Donald Trump has further shown his seriousness about promoting crypto-friendly policies if elected president. Politicians cannot be trusted but at least this is a candidate who has firmly opposed anti-crypto laws in the Senate and has openly criticized SEC's policy mandating banks to report crypto as liabilities on their financial books. He is young and owns Bitcoin, I am beginning to see Trump's sincerity regarding his pro-crypto stance. It is also possible that this move is to gain financial support and attract young voters, only time will tell.
