I really hope your predection comes out. But i think 2020 is a little bit too early for that. That it will be higher than the price of almost 780 dollar now, that is for sure i think. I think it is more possible that the price will go with a few hundred dollar upwards every your. Hope to end at 2020 dollor in 2020. That should be beautiful. I think that is more realistic than 50000.
