There are a few things that need to be considered when trying to predict Trump's influence on Bitcoin.
Trump is a very successful business man so he will see value in it for what it is but....
He also said that one of his main platforms is that he would like to bring a lot of the US's business back to the US to strengthen the economy. I found this hard to believe because, most businesses do source out the manufacturing and labor because, it is cheaper. Trump himself has sourced much of his business outside of the US. Regardless, it was one of his platforms.
If Trump sees BTC as a threat to the value of the US dollar, or more likely the US economy he very well could issue restrictions on BTC.
If none of this comes up then why would he mess with Bitcoin???
