I think the future of bitcoin will be defined in terms of banks and the establishment versus the world.
One one side, we have independence movements like #brexit, catalan independence and others who are dissatisfied and unhappy with the pro establishment status quo. Nations like iceland, hungary and others who borrowed money from the IMF during the economic crisis of 2008 then kicked the IMF out of their country after they realized the price of borrowing money from them was for them to interfere in their politics and infringe upon sovereign rights may also be considered affiliated.
On the other side we have organizations like the european union, IMF and central banks which represent an attempt to centralize and unify the entire world and its money supply under their own solitary rule.
I think independence movements like catalan and #brexit will eventually embrace bitcoin and crypto as it will give them independence from SWIFT and other banker financial networks while central banks be attempt to ban crypto and outlaw it. Of course they have other alternative plans such as having banks regulate crypto or buying up all of the exchanges as we have seen goldman recently buy out poloniex.
Who knows what the outcome will be but I think bitcoin's future could be defined in terms of this conflict.
There is a lot of potential in these currencies for future use as in future these short payment method will be adopted for daily use as they are very simple for use and these are very best for payments
