South Carolina Republican Rep. Sheri Biggs snapped up between $100,001 and $250,000 in shares of BlackRock's spot Bitcoin ETF (IBIT) on March 28, according to a new financial disclosure, doubling down on a position she first entered last July as Congress members increasingly eye Bitcoin ETF investments amid surging crypto market trends. This move aligns with broader interest in BTC from U.S. lawmakers, following disclosures of similar holdings in the past year, positioning her portfolio for potential gains in the evolving Bitcoin price prediction landscape.

Zooming into the 4h BTC chart, price action holds firm at $77,344 in a clear bullish structure, hugging the upper Bollinger Band resistance near $77,378 while the MACD screams golden cross momentum at 1,008—a setup screaming continuation if we punch through. Yet with RSI flirting at 69, just shy of overbought, expect some profit-taking pullback to test the rock-solid EMA50 support around $73,647, where confluence with the EMA200 at $70,943 could reload bulls for the next leg up, especially as volatility bands suggest exhaustion isn't far off.
