Bitcoin’s story has taken a new twist since U. S. regulators approved spot Bitcoin ETFs. The iShares Bitcoin Trust (IBIT) grew faster than any other fund, pulling billions into a regulated wrapper. What followed was the rapid rise of options on that ETF, which now holds more Bitcoin volatility than traditional crypto futures exchanges.

When traders buy calls or puts on IBIT, dealers must hedge their positions. Because the ETF owns real Bitcoin, those hedges spill over into the underlying market. This creates a feedback loop: as Bitcoin moves, dealers buy or sell spot to stay balanced, which can push prices up or down even more. The effect is similar to what happens with equity indices, where market makers adjust their bets in response to option flows.

In February, Bitcoin fell hard while the ETF’s options market was still calm. Instead of panic selling, the fund actually added new shares. Analysts say that large multi‑strategy funds were pulling out of risky positions across many assets, including Bitcoin. The ETF’s options had a short‑gamma stance—meaning dealers were short on convexity—and as prices dropped, they sold into the decline. When the market recovered, they bought back, helping Bitcoin bounce back.

Because of these mechanics, Bitcoin’s link to traditional markets has grown. Its correlation with the Nasdaq has nearly doubled since the options started trading, showing that Bitcoin is no longer a purely digital asset but part of the broader financial system. This shift challenges the “digital gold” label and suggests that short‑term price swings are driven more by institutional hedging than by pure supply and demand.

For long‑term investors, the core value of Bitcoin as scarce digital gold remains. Yet day traders and portfolio managers must now watch how ETF option flows influence price swings, especially during U. S. market hours when most activity happens.
