Sideways movement usually indicates something much bigger is about to happen.
What i think is most likely to happen is first another pump that will potentially push bitcoin over $4500(maybe even $5000, i'm not sure about the specifics), and gets everyone hyped up again. And then the correction will come arounda week later, and people will start panic selling.
The correction is definitely going to come, sooner or later. We just don't know exactly when it's going to happen but it's going to happen this year or the start of next year. No way we are going to avoid it when the price has moved upwards so fast, for essentially no reason or very little reason. It is pure speculation, and we've seen that in history it has always resulted in a sizeable adjustment in the end.
