:)Countries are divided into 3 groups: those who ban bitcoin, those who will regulate it strongly and those who will give complete freedom to development. The second and the third groups us well be satisfied with. This majority. It's enough to survive.Therefore, it is not necessary to look for negative outside of us. ; 
I agree to you that there is no such thing to think negative about bitcoin in the future, but as what you said that country are divided into three groups, the first one you said: those who ban bitcoin, will become the problem because it may influence the other country and may affect the future of bitcoin. But on the other side the other two groups can change bitcoin in the future and I hope they can helps more people by giving it a good development.
