According to @TO, three new 4 MB “4 meggers” inscriptions just hit the Bitcoin network, with the first titled “Preserving history on Bitcoin” (source: @TO on X, Dec 11, 2025). A 4 MB inscription approaches Bitcoin’s 4,000,000 weight-unit block limit introduced with SegWit, meaning a single transaction can occupy most of a block and reduce concurrent throughput (source: Bitcoin Core documentation; Bitcoin.org Developer Guide). When large inscriptions consume blockspace, required feerates for timely confirmation tend to rise as the mempool grows, lifting on-chain transaction costs (source: Bitcoin.org Developer Guide; mempool.space fee estimation methodology). Traders should track real-time sat/vB fee tiers and mempool size to time on-chain moves during inscription waves (source: mempool.space explorer). Monitoring the share of miner revenue from fees offers a read on fee pressure during congestion (source: Blockchain.com Charts, Miners’ revenue from fees).

According to the source, 95% of Iran's crypto miners operate illegally, straining the national power grid. Source: X post dated Nov 2, 2025. Iran has previously curtailed electricity to crypto mining centers during peak demand to protect the grid, indicating elevated enforcement risk during stress periods. Source: Reuters, June 2022. For traders, curtailments can introduce short-term BTC hashrate variability and subsequent difficulty adjustments that affect block intervals and fee dynamics; Bitcoin difficulty adjusts roughly every 2016 blocks. Sources: Bitcoin.org protocol documentation; Reuters, June 2022. Actionable watchlist: monitor BTC hashrate and mempool fees, miner revenue per TH/s, and upcoming difficulty estimates for signs of network impact tied to Iran's grid strain and illegal mining prevalence.

According to @BitMEXResearch, a tiny minority in Bitcoin can relax an incentive-incompatible network relay limit regardless of majority preferences, while a significant minority can still enforce existing consensus rules, source: @BitMEXResearch. For traders, this asymmetry signals potential shifts in mempool relay behavior and fee dynamics that can impact BTC confirmation times and short-term liquidity conditions, source: @BitMEXResearch. Actionable focus includes monitoring relay-policy discussions, client policy updates, and on-chain fee spikes as early indicators of policy divergence that may widen BTC perpetual spreads and alter options skew, source: @BitMEXResearch.
