According to @BTC_Analysis, Bitcoin dominance is rebounding from a key support level, signaling renewed pressure on altcoins as capital flows favor BTC over alternative cryptocurrencies. Traders should monitor BTC.D charts closely, as historical patterns suggest that rising Bitcoin dominance often coincides with altcoin underperformance and increased volatility in the altcoin sector (source: @BTC_Analysis on Twitter, June 2024). This shift may prompt portfolio rebalancing and risk-off approaches for altcoin-heavy investors.
