Myths and facts about Red September and Uptober

The last warm days for the crypto community used to be a panic: “September is the worst month for BTC and crypto in general!” they say. That’s why it’s called Red September — the time when the main crypto falls each first month of fall since 2013.

The biggest fall occurred in 2019, when Bitcoin dropped by 13.38%.


Breaking the cycle

For the last several years, BTC has changed its fall behavior.

In 2023, it showed the largest increase of all Septembers — 7.29%! The truth is, dipping happened due to seasonality, tax-loss selling, and low trading activity. But in the last two years, stronger institutional demand and shifting market sentiment pushed it upward instead.

The highest rise of Bitcoin happened in October 2013, when the first cryptocurrency rose by 60.79%. See the whole history yourself:

The reasons why it's happening may vary — fresh inflows, improved sentiment, and anticipation of year-end rallies often drive the price up.

Maybe it’s all just a coincidence?

While many traders point to Red September and Uptober as clear market patterns, they could just be coincidences shaped by psychology rather than real seasonality. This explains why BTC has been rising in September over the last several years. When enough investors expect the first fall month to be bearish, they may sell earlier, reinforcing the drop.

The same works in October — optimism and memes around Uptober can create a self-fulfilling rally, while in reality, October wasn’t always this successful for Bitcoin. In the end, these trends might be more about collective belief than actual market fundamentals.

Should you listen to anyone? It’s up to you. All we know is that ones who don’t stop mining through Red September and Uptober live the best life!
