Rumors of Bitcoin ETF approval typically boost market liquidity by attracting speculative traders anticipating price surges. Increased trading volume results from heightened interest, as retail and institutional investors enter the market, expecting regulatory validation to drive demand. This influx narrows bid-ask spreads and improves price discovery. Investors often adopt short-term strategies, such as day trading or swing trading, to capitalize on volatility. However, savvy investors may also hedge positions with futures or options to mitigate risks if the approval fails to materialize or triggers a "sell the news" event.
