My guess is 10.000$ all time high before block halving.
Call me crazy or whatever you want, but I believe in this. We wait for 2 years. Now it's our time!
$10k is only possible after 2020 block halving. At that time, the block halving is not as important as the block reward is relatively small. With 17 million bitcoin, $10 price increase means $170M market capitalization increase.
