I am not surprised to see Bitcoin and cryptocurrencies appear more in propaganda of President election candidates in coming months. They know that blockchain, cryptocurrencies especially Bitcoin have become more attractive in the USA, among their citizens amidst the uncertainty of their financial system, their economic recession and some bank collapses recently.
Nobody can feel safely with stocks of banks as they, as stock investors, won't be protected by FDIC, and that triggered massive panic sales on many bank stocks.
With Bitcoin, they know that they will have a better asset of trading, investment, or as inheritance for their children too.
More politicians will do what Robert Kenedy Jr. did to attract more supporters for their campaigns and their political career.
Politicians know very well that bitcoin is very popular among the young voters, so most likely it is going to be a topic that is going to be brought forward over and over again in order to gain the support of that sector of the population.
However even if that is true he is not wrong about his views about the policies the current president is taking, the US became the most powerful country around the world by supporting innovation and being the first to adopt all kind of new technologies, by taking the opposite stance Biden is driving innovation and prosperity out of the US while some other countries will be the ones to reap the benefits while the US gets nothing.
