Going back a full month, in late August or early September, many people on several site and on the cryptocurrency Twitter were suddenly very vocal in saying that September was bound to be bearish for Bitcoin because the previous two had seen significant dips and because September is simply historically one of the worst performing months for cryptocurrency.
But this time was different: 
Here, we can see that despite the lack of significant bullish news, with the possible exception of the release of the Ethereum ETFs, September did close a full +3.9% higher than August. Even so, with such low levels of liquidity as they are at the moment, we don't need much news to impact prices.
In any case, this is yet another example of how previous performance is not a guarantee of future performance. While I personally believe that the past will always and forever be a part of the future, many people simply have a tendency to anticipate the future and base their financial decisions on the past, which I believe to be reckless and nothing more than gambling.
While history can never be exactly the same, it does frequently rhyme, therefore this does not mean that we should dismiss it entirely. The past, present, and future must all be balanced, and we must pay attention to both the past and the present as well as the future.
