Like any president, Trump is taking credit for good economic news. his highlighted rising stocks and falling unemployment. But Trump also, famously, regards trade deficits as a sign of economic weakness.
he's doing better than his opponents will admit and worse than his supporters believe.
The trump is a very broad view of economics, so I think he will know how to make cryptocurrence a valuable money exchange. But it is very unlikely that he is focusing on other things and the cryptocurrence is not big enough for him to care.
