According to @crypto_birb, Bitcoin has shown significant bullish momentum as it broke above the $68,000 resistance, signaling potential for further upside in 2024. The analyst highlights that a sustained move above this level could lead to a retest of the $72,000 area, which may trigger increased trading volumes and bullish sentiment across the crypto market (Source: @crypto_birb on Twitter, June 2024). Traders are advised to monitor key support at $66,000 for risk management, as a drop below this level might indicate short-term weakness. The broader altcoin market is also expected to benefit from Bitcoin's strength, with Ethereum and Solana highlighted as potential outperformers if bullish momentum continues (Source: @crypto_birb).
