Don't really know what would happen with bitcoin in the future but for now I believe it's at highest peak and is not gonna drop down to like 5-6 years. That will be insane if it really happens but I don't see any reasons for that to happen. Bitcoin has already gotten developments done which were necessary to push it to the current situation. Bitcoin will now keep growing from here onwards with little drops. I have observed bitcoin goes up to highest peak and then get stabilised to that point really.
