币界网报道：Bitcoin's correlation with growth stocks has surged to its highest level in over a year, signaling increasing institutional adoption and market maturity, according to recent data. The 90-day correlation coefficient between Bitcoin and the Nasdaq 100 reached 0.46 in late January, nearing levels last seen during the 2021 bull run. Analysts suggest this growing linkage reflects Bitcoin's evolving role as a risk asset in institutional portfolios, rather than just a speculative alternative investment. The trend coincides with rising institutional participation through spot Bitcoin ETFs, which have attracted over $4 billion in net inflows since launching in January. Market observers note this development may reduce Bitcoin's volatility while potentially exposing it to broader macroeconomic risks affecting traditional markets.
