Well searches for "bitcoin halving" have been skyrocketing on google for a couple weeks now, and we saw bitcoin rally from about $7k to $9.5k during this same time period... Given that, I would not be surprised to see a retrace down to $7k, possibly into the $6k's post halving once price doesn't immediately moon.
I do concede that the drop we had down to $3.8k wasn't a normal drop and wasn't "supposed" to happen, but people tend to trade recent price action and not where prices were "supposed" to be going in. If they bought at $7k and the price is $9k, and things start to look weak, there is a good chance they pull the sell trigger, irregardless of the fact that the price "should" have been trading for $10k going into the halving flat. IE, the dip creates sellers as they are sitting on profit that they otherwise wouldn't have been.
