On Trump support of Bitcoin and crypto, I agree.
He uses his prestigious office to talk about Bitcoin in a positive light. No other president has done this. Since Trump won the election with a majority, there is the sense that these supporters of him will be open to buying Bitcoin when they hear him talking about it.
