Bitcoin surged today above $121,000, hitting an all-time high as the fourth quarter of 2025 kicked off with a new momentum for Bitcoin.
The rally follows a strong September finish when Bitcoin earns around 5% and closes around $114,000.
Historically, when September ended on the green, Bitcoin often achieved four quarters. According to data from Bitcoin Magazine Pro, 4th quarter meetings averaged over 50% in years such as 2015, 2016, 2023 and 2024.
That seasonal trend has already won the nickname “Up to Ber” among traders in October. Since 2015, the month has averaged an increase of 21.8%, with November adding another 10.8%.
If history rhymes, Bitcoin can get on track to clear $150,000 by the end of the year.
Is Bitcoin’s greatest arrival?
Bitcoin has risen nearly 3% in 24 hours, moving from around $117,500 to over $121,000, according to data from Bitcoin Magazine Pro. Last month, Bitcoin made more than 9% profit, up from around $110,700.
Since the start of the year, Bitcoin has provided a 27% return, highlighting its resilience despite ongoing volatility in the broader market.
Currently, it’s under 3% from a high above $124,000 from an all-time high, so if the purchase pressure continues, the stage appears to be set to a breakout.
Bitcoin’s bullish momentum
This latest surge comes when traditional economic indicators caught up in midnight after Congress failed to pass the funding bill. Investors flocked to hard assets as Wall Street is under pressure and economic data is being released.
This year’s profits also became the harving event in April, cutting new Bitcoin supply by half. At the same time, the main fluidity signal is flushing green.
Growth of global M2 money supply, Stablecoin issuance, and gold gatherings (which Bitcoin often tracks in lags) refer to strengthening demand.
Citigroup analysts set a 12-month Bitcoin forecast at $181,000 this week, citing a robust influx that could reach $7.5 billion by December.
“In comparison to ether, we are more positive in Bitcoin, as we capture a large portion of incremental flow into the crypto market,” wrote a city analyst, adding that a friendly regulatory environment will be able to maintain momentum in 2026.
With Bitcoin already hitting record highs in 2025, the fourth quarter is approaching a decisive stretch.
