Yes, I also don't think September will be a good month for Bitcoin, most likely we will see another market decline, but that doesn't worry me because these fluctuations are normal in the market.
According to the latest analyses I've read, Bitcoin needs its final jump within 3-4 months, after which its dominance will decline and open the way for altcoins. This means that we probably won't see a significant rise in Bitcoin before the end of the year.
In the end, these are all analyses and there are many variables in the market that can overturn all these analyses, so we just have to wait and watch.
