The President is a businessman and real property investor, its pretty sure he knew how stock market works. I can only presume he has BTC investment as well but just don't worry about price as he knows it going to go up no matter how hard the fuds will be. It would be so much better if he just express support to BTC though. It would have reached up to 14k by now.
Trump is not the type of business person to chase after flashy tech stocks or Bitcoin. He's somewhat similar to Warren Buffett in the way that he likes to invest in properties, businesses, etc. In other words, anything with a cash flow and a possibility to earn dividends.
When people are a multi millionaire or a billionaire, they are looking for ways to preserve their wealth, and Bitcoin for these traditional investors poses an incredible threat to their wealth. They invest in things that have proven themselves, have a working product, Bitcoin is nothing like that from how they look at it.
People here shouldn't hope for presidents or other high level entities to share with the world that they love Bitcoin and own a ton of it. It makes me even think people find it necessary for them to jump into Bitcoin in order for it to succeed. Bitcoin has never given a shit about who owns whatever amount of coins, neither should you.
