Bitcoin block height as a New Year marker: Universal Bitcoin Time concept and its legal limits
On Dec. 27, 2025, Bitcoin block 929,699 was mined, raising a thought experiment about using block height as a universal New Year reference instead of the civil calendar. The proposal treats consensus-verified block counts as a shared time layer for cross-border settlement, but the stochastic nature of block discovery creates multi-day uncertainty bands around any “year-end” block target. While exchanges and custodians could anchor reports and proofs to specific block hashes, tax rules and statutory reporting remain tied to jurisdictional time, forcing users and institutions to navigate block time and wall-clock time in parallel.

Michael Saylor’s "Back to Orange" Post Sparks Talk of Fresh Bitcoin Accumulation on 28 December 2025

The brief update did not include any confirmation of new purchases or transaction details but revived debate over the firm's long-term approach. With Bitcoin consolidating in the high-$80,000 range and key indicators such as RSI and MACD showing cooling momentum, some traders see the current setup as consistent with Strategy's historically conviction-driven buying phases.
