For this time anything can happen. but I think that the world will switch to another payment system, the world financial revolution will take place 
LOL. 2025 is still far. But I speculate that the price is bitcoin have reach the 5 digit mark so I don't know if its still a viable choice for making online payments. Because ordinary and casuals can't get it because the price is too high. And maybe it will just be a good investment portfolio and nothing more. So I don't think that it will be adopted by a lot of countries because of the price.
We can never say, there is a lot of possibilities that might happen in the future, war might surface anytime, a number of disaster and plagues predicting the future is impossible right now I think we should aim earning and attaining bitcoin for now and hope that the value would still increase for more years to come because bitcoin is very limited in the years to come that is why the value will surely surge high because of the demand and when that time comes you would be one of the millionaire.
