Historical Patterns Show September Triple Witching Impact

Looking at the data from 2000 to 2025, the S&P 500 often experiences a decline in the week after triple witching. Like in

  • 2000: -1.17%

  • 2011: -6.54%

  • 2022- -4.65%

  • 2023: -2.93%

  • Bitcoin prediction: 5-8% dip possible, from the current price of approximately $116K it might fall to about $110k-$106k. .  

  • Altcoin crash prediction: 15-20% potential decline in prices

This matches with the general trend of equities that is hinting at cautious optimism for crypto users looking at altcoin crypto opportunities. 

It might also be possible that if the Fed reduced the rate then a surge in prices could be seen, BTC currently trading around $116k might reach to $120k, whereas Alt will also show positive signals despite the dips.

  • BTC price prediction trends and its movements in prices.
