September if you will look at the charts is really a bad month for Bitcoin but the remaining 3 months is one of the best months of it. I'm not saying though that from October - December, price of Bitcoin don't go down but if you will look at the history you will see that most of the time it goes up.
I think there is no need for an explanation into what is happening this month because it is expected already base on the history. One thing more is that the bulls are still in control of the market. We almost saw the Bears controlling it by seeing Bitcoin went down to below $30,000 but it didn't happen and instead the bulls prevail.
the month of october bitcoin has gone too far to climb, could it be that he has reached the end of the mountain or is still in the process of climbing it. I'm a little worried about the current state of the market, if bitcoin is at the end of the climb it might come back down to take the next mountain. hopefully bitcoin continues the process of climbing high mountains reaching the latest ATH price.
