Finally, I could not find a valid reason for the upward trend, and I could not find any news to trigger this rise. Although I came across some news and articles in various sources, unfortunately, I have seen that these contents do not give much information about the details. If we think of a few possibilities of this rise, we can immediately notice the fact that we may have a new carp hunt. Of course, if this is not the case, we can think that new investors enter the market with serious budgets. That is, there is no valid reason for this recent upward fluctuation, but there is no serious retreat.
The lack of valid reasons for the new trend make articles authors write anything justifying why bitcoin is rising so fast. Then there is a lot of weak points and speculation explaining why bitcoin is doing so well now, it doesn't give any idea of what is really happening.
Probably it's just someone or a small group pumping btc and some other people following the trend. At least it's good news to show to the skeptics bitcoin isn't dead.
