The next president that can make Bitcoin bullish aside from Donald Trump, has to be the president of China, in global economy when you mention USA the next country that comes to mind is China, no doubt about that. If you consider China's unfriendly attitude towards Bitcoin it's very unlikely that they will make any policies that can make Bitcoin to be bullish, except if they change their perception which I don't see happening anytime soon. I am glad that Bitcoin has the potentials to be bullish in it's circles without a huge influence like china, pulling it's strings to be bullish. Top European countries can cause impact that can make Bitcoin to be bullish but none can be compared to china, that has the population and global economic impact.
