Its not accepted globally, and the value price can not be predicted its up and down..price not stable. So if you are not careful you lost all of your bitcoin due to exchange and its up and down value...
yes that is a fact that there is a lot of fluctuation in the price of bitcoin which worry people to invest in bitcoin because the price of bitcoin can fell down over night and one can lose all his investment, but to me the other problem that we face in using bitcoin is that we have very little opportunities of using bitcoin in our local areas,
