In 2016 the halving was early July. Depending on the exchange, the price was as follows:
May 1, 2016 $453
June 1, 2016 $536
July 1, 2016 just before the halving $677
The price increased about 50% from May 1 to July 1 just before the halving event.
Should we expect something similar this time?
Expect, no. Possible and likely, yes.
Looking at the price 6 months before halvings and 12 months after has resulted in large fiat gains. Betting against it is a bad idea.
This year after the halving, there are more uses, more people aware of those uses, and a much smaller new supply as compared to the previous halvings. So more demand, less supply leads one to think it is likely the price will increase.
