Are you betting on a Bitcoin bull market? Not in September, BTC price data says

Bitcoin (BTC) may score a new all-time high in 2021, but the odds are that it won't happen next month.

Historical price data confirms that September tends to see BTC price losses -- and its best-ever returns are still single figures.

September 2021 seems like a classic month for Bitcoin

As Bitcoin matures, it is more obvious that BTC/USD behaves similarly in the same month every year.

The clear standout in terms of top performance is Q4, especially after a block subsidy reduction. However, January tends towards bearishness -- though this year was an exception to the rule.

Investors are not encouraged by the September picture. Although summer may be over, historically, Bitcoin has not increased by more than 6 percent in September.

"Bitcoin doesn't like September at all," Cointelegraph contributor Michael van de Poppe commented this week.

"Are we going repeat and have a correction month across the markets, before continuing with bull cycle?"

Better luck in Q4?

Already, September is expected to have a slightly lower price range than August. PlanB, the creator of the stock/to-flow Bitcoin price models said that this was a technicality.

However, Bitcoiners don't have to smile and bear it long as October tends not to provide much convincing momentum.

However, for now, it appears that a retest at all-time highs is unlikely. BTC/USD was trading at $47,600 at the time of writing. It had lost approximately 1.6% over the last 24 hours.
