The question is very interesting, like you want to invest but do not want to lose. I think this will never happen because the only loss is to give you more experience to make the right decision. The current Bitcoin rates are down to $ 13,000, which is a good investment if you want to invest Bitcoin in the long run as it predicts that by the end of 2018 Bitcoin will reach $ 100,000.

I think the main reason is their technology still not developed enough to control Bitcoin and its disadvantages as well. Bitcoin has both advantage and disadvantage. A country will not legalize Bitcoin unless they can be able to control Bitcoin totally both advantage and disadvantage.
