UP of course!
I would guess the next leg up will happen a couple months after the halving, maybe September. Until then, price will probably go mostly sideways, bouncing around in the 600s.
Markets take some time to process new information, and I would expect the effects of reduced supply from the halving will take a few months to work their way through the market. I think the halving will produce more upward price pressure than most people expect, so the market should correct upward. Combined with the organic usage growth we are seeing, there is huge upward price pressure. Organic growth tends to be strongest at the end of summer.
The biggest uncertainty is the transaction capacity limit. Even without resolving the block size problem, I think there's enough market pressure to keep the price grinding upward. But if the capacity constraints are resolved in a more decisive way, then we could be on the brink of explosive growth.
