Rumors of Bitcoin ETF approval are resurfacing, potentially impacting BTC price significantly. Historically, such rumors have driven short-term price surges, as seen in October 2023 when false ETF news pushed BTC to $30,000. Approval could attract institutional investors, increasing demand and tightening supply, especially with Bitcoin's fixed 21 million cap. However, a "buy the rumor, sell the news" scenario might trigger a post-approval dip if expectations overestimate immediate inflows. Market sentiment on X remains bullish, but volatility is expected.
