Why did bitcoin rise in tandem with the S&P 500?

Could you elaborate on the recent correlation between Bitcoin's price surge and the performance of the S&P 500 index? Is it merely a coincidence, or is there a deeper financial relationship? How have investors' perceptions of Bitcoin as a potential asset class evolved to align with traditional market indices? What factors might be driving this parallel rise, and how might it affect the broader financial landscape in the future? Is it sustainable, or are we witnessing a temporary phenomenon? I'm keen to understand the underlying dynamics behind this intriguing correlation.
