Why is Bitcoin moving today?

Bitcoin is down 1.0% on the day to $81,482, a modest drift rather than a break, and the clearest macro trigger is inflation. CoinShares says hotter-than-expected inflation data has put bitcoin "under pressure," though the asset manager framed the backdrop as "difficult" rather than bearish for long-term holders.

The second weight is structural. MSCI has finalized rules classifying "non-operating companies" as ineligible for its equity indexes from Nov. 30, a change that could eject bitcoin treasury firms such as Strategy and Metaplanet and force passive outflows from the vehicles that have absorbed large amounts of supply. Sentiment is also being nicked by security headlines: Mark Karpelès says a spy implant turned up in a Ledger Flex and Nano X from two more authorized resellers, while Google's latest quantum computing milestone has revived questions about the cryptography underpinning bitcoin.

There is offsetting institutional news. Deutsche Bank is nearing launch of institutional bitcoin and ether custody, and Strive is raising $500 million via preferred stock to buy more bitcoin, earning a 27% price target hike from TD Cowen. Mining difficulty also jumped 5.92% to 140.58 trillion.
