Bitcoin exchange-traded funds (ETFs) in the United States have rebounded with $477 million in net gains recorded on Tuesday, following weeks of outflows. This resurgence is seen as a precursor to a potential Q4 rotation, where investors might shift focus from Bitcoin to altcoins such as Dogecoin (DOGE), TRON (TRX), and Chainlink (LINK). Dogecoin is experiencing increased retail interest due to new integrations, while TRON is enhancing its network capabilities and expanding interoperability. Chainlink is drawing institutional attention, evidenced by rising whale activity. October's net inflows into Bitcoin ETFs have surpassed $4 billion, exceeding September's figures, indicating a robust market sentiment.
