I believe that Donald Trump will accelerate Bitcoin adoption... as some sort of global reserve asset, global reserve property. And the exchange rate will moon big-time.
But I also believe it could be like the Tortoise vs the Hare - Red Hare and Blue Tortoise and I'm not sure the effects are 'long-term' yet.
If we get Bitcoin as an actual 'strategic reserve asset', supported by the US president (which the US already has anyway) it could have a huge impact.
