Cryptocurrencies are down on Tuesday morning, with Bitcoin retracing back to $113,000 ahead of a pivotal U.S. government shutdown negotiation. Trader Notes: Crypto trader Niels highlighted that rising Bitcoin dominance is actually bullish for altcoins. As BTC strengthens, the cycle remains intact, creating prime accumulation windows before altcoins potentially go parabolic. Dips in the coming weeks are seen as opportunities to buy.
