Never. This is impossible
Although it is really hard to believe that Bitcoin can cost a million, it might happen. However, many years will pass, and for this only a few BTC should be remained.
It is hard to happen this year or in the coming year, but yes it is not way impossible. It is going to happen when we all are going to support bitcoin to bits in its hard and good times. Bitcoin is not going to deceive us in any way, this is my firm belief in bitcoin. We all bitcoiners should do maximum efforts to promote it in order to touch 1 million dollars as soon as possible. We are going to rock then the whole world.
