The current scenario is really downward so no one is accepting the 50k USD in end of the year.
May be some unexpectable positive news are comes in future it will reach 50k USD. But surely it is impossible in this year.
Although $50k seem to be on the high side but no body is entitled to predict price because we saw the growth of last year. However that move, I strongly doubt that to happen, market have not been up at all to speculate that.
