For some reason, we used to consider 2017 as a very successful year for Bitcoin. But if you recall October 2017, the situation with the course of Bitcoin looked no less sad than it is now. It rapidly fell, but already in December there was a colossal growth that agitated all market participants. So everything can be repeated, because Bitcoin has no limitations in time, or in the degree of growth or fall.
That should happen this year as well in my opinion. The reason is that people are spending more in festive season and this is why you will see all types of promotional offers being launched by different companies in this time of the year only.
You are right when you say that it could be repeated again, but what are the odds that is going to happen at the end of this year? And if you think about it the odds are not very good, the odds were great at the end of the previous year because we had several good news in a row that made people very positive about the development of bitcoin and its future but now there is nothing like that in the horizon and there is no indication of that happening soon.
