Trump follows good investments, if Bitcoin is the frontrunner of the economy Trump will follow. This is just my opinion, i have no data to back this up.
Bitcoin was a good investment at $10-$50 at the current valuation this is not something a mega rich billionaire gives a turd about or would class as a good investment
Maybe investing in his own crypto would be a possibility but doubtful and it is unlikely he will care about Bitcoin, unless a 3 letter agency puts in on his radar to be dealt with of course. Again doubtful.
