Bitcoin hitting $95k triggered the biggest day of ETF inflows in three months, with about $754M flowing into spot ETFs on Jan 13. Fidelity's FBTC led the way with $351M in net inflows, followed by Bitwise and BlackRock. Analysts think this is mostly due to institutional rebalancing after tax season and better macro sentiment. The rally spilled over to altcoins too, with XRP, Solana and Dogecoin up 2-6%. There is some optimism around a new draft bill that could give these assets clearer regulatory status. Despite the high volume, analysts expect institutional demand to remain cautious in Q1 as long as interest rates stay elevated.
