I don't think you're right that you can just force a new digital currency through - Bitcoin has arguably succeeded because it is decentralised and separate from government interference. Trump might introduce new regulations around digital currencies but I doubt that will happen for a couple years and will be more targeted towards generating tax revenue. The only reason mining moved over to China is because they actively supported it as a revenue stream and utilised cheap power sources like hydro electric dams. Bitcoin might be high right now, but gold has held it's value for a much longer time historically.
