Donald Trump uses Bitcoin to purchase hamburger
... The Trump I know would have spoken about the history he made and acknowledged the cheers from people around. Nevertheless, he has made history as the first ex-president to use Bitcoin publicly. All these political stunts are targeted at getting more votes and donations from the crypto community.
Spot on. All this political show was probably an idea of someone very close to Trump and aware of the popularity he currently has within the Bitcoin community, because of the stuff he has said, he was convinced to do this by some of his aidees so he can continue to collect more for his campaign (at this point, I don't know how much money he actually needs to keep running his campaign, to be honest, keeping in mind he is being funneled money from Elon Musk and other people within the elite).
Also, the news of Trump escaping another assassination attempt while he was playing golf does not have anything to do with the fact he decided to become the first ex-president to ever use Bitcoin.
