Adam Back: Bitcoin Anti-Censorship Makes Spam Defense Harder — What BTC Traders Should Track Now
According to @adam3us (Twitter, Oct 5, 2025), fighting spam is an arms race and is harder on Bitcoin because of its anti-censorship design. Bitcoin relies on transaction fees and limited block space to deter spam, which creates a fee-bidding market under congestion that impacts confirmation times and on-chain costs (source: Satoshi Nakamoto, Bitcoin: A Peer-to-Peer Electronic Cash System, 2008; Bitcoin.org Developer Guide – Transactions and Fees). Traders can manage execution risk by monitoring mempool size and sat/vB fee bands to plan BTC settlement timing and costs during congestion cycles (source: Bitcoin.org Developer Guide – Mempool and Fees). |

Bitcoin BTC Future Debate 2025: Halving-Driven Miner Economics, On-Chain Fees, and US Spot ETF Flows Guide Trading Setups
According to the source, traders are centering their BTC playbooks on three verified drivers: miner economics after the April 2024 halving reduced the block subsidy to 3.125 BTC at height 840000, persistent on-chain fee pressure from inscription activity, and the liquidity impact of US spot ETF primary flows. Source: Bitcoin.org; mempool.space; U.S. Securities and Exchange Commission. The halving mechanically lowered baseline miner revenue, increasing sensitivity to fee cycles and BTC price for hashprice and potential treasury adjustments observable in industry hashprice indices.

Bitcoin (BTC) Is Ungovernable: BitMEX Research Says Core’s Full-RBF, Min Relay Fee, OP_RETURN Filters Failed — What Traders Need to Know
According to @BitMEXResearch, Bitcoin Core’s attempts to curb full-RBF via policy filters failed and were reversed by the network, indicating client defaults could not override miner and node preferences (source: BitMEX Research on X). According to @BitMEXResearch, efforts to impose a minimum relay fee filter also failed and were subsequently dropped in favor of network behavior, highlighting that fee propagation is dictated by market participants rather than Core settings (source: BitMEX Research on X). According to @BitMEXResearch, attempts to block large OP_RETURN data similarly failed and were rolled back, reinforcing that Bitcoin’s transaction policies are ultimately set by the network’s will, not centralized governance (source: BitMEX Research on X). According to @BitMEXResearch, traders should frame execution risk around mempool-driven dynamics—RBF usage, relay fee preferences, and miner policy signaling—since fee volatility and confirmations follow network incentives, not Core filters (source: BitMEX Research on X). |

Adam Back Flags Blocks-Only Bitcoin Nodes: 3 Key Trading Impacts on BTC Fee Signals and Settlement
According to @adam3us, some Bitcoin Knots proponents may prefer operating blocks-only nodes to reduce exposure, likening the setup to leech mode in peer-to-peer file sharing, source: Adam Back via X. In blocks-only mode, nodes do not request or relay unconfirmed transactions and synchronize primarily through blocks, which limits local mempool visibility used for fee estimation and confirmation targeting, source: Bitcoin Core -blocksonly documentation. For BTC traders, reduced participation in mempool relay can make widely tracked fee-rate and mempool-size indicators less representative during congestion, affecting predictability of on-chain settlement times, source: Bitcoin Core -blocksonly documentation. Short-term execution strategies that rely on unconfirmed transaction flow should incorporate multiple full-relay data feeds or direct miner interfaces to mitigate blind spots, source: Bitcoin Core -blocksonly documentation. |

Bitcoin OP_RETURN Governance Debate Spurs Backlash; Policy Not Consensus Change Puts BTC Traders On Alert
According to Patrick McCorry, the current Bitcoin OP_RETURN governance dispute has turned toxic despite not involving a consensus rule change, highlighting that the issue is about policy-level standardness rather than base consensus. Source: Patrick McCorry on X. In Bitcoin Core, OP_RETURN handling is governed by standardness policy and not consensus, allowing nodes and miners to independently choose relay and inclusion behavior, which can alter transaction propagation and block composition. Source: Bitcoin Core documentation. Relay and inclusion policies directly affect mempool backlog and fee rates that traders monitor when assessing BTC liquidity and intraday volatility, making mempool size, feerate bands, and miner inclusion patterns key signals around this debate.

BTC Fee Market Alert: Adam Back Urges Miners to Avoid 'JPEGs' via Pool Shifts and Economic Lobbying — 3 On-Chain Signals for Traders
According to @adam3us, nudging miners with education, outreach to switch to pools that do not include image-style 'JPEG' transactions, and fee-backed economic lobbying could reduce their inclusion in BTC blocks, indicating a push for stricter pool-level transaction policies, source: Adam Back (X, Sep 5, 2025). A coordinated mining-pool policy directly changes block templates and which transactions compete for scarce block space, thereby influencing the Bitcoin fee market, source: Bitcoin.org Developer Guide on Mining and Transaction Fees. Traders should monitor pool policy announcements, the share of blocks mined by pools that exclude such transactions, and median sat/vB fee levels as near-term catalysts for BTC on-chain costs and throughput, source: Bitcoin.org Mining overview; mining pool operator communications. A visible decline in these image-style transactions would be reflected in mempool composition and block contents, signaling potential easing of fee spikes that impact deposit and withdrawal costs for exchanges and users, source: Bitcoin.org Mempool and Fees documentation. |

Adam Back Says Bitcoin P2P Filters Don’t Work: What Traders Should Watch for BTC Fees, Mempool and Miner Revenue
According to @adam3us, Bitcoin transaction relay filters "don’t work," and conflating the mempool with the peer-to-peer network misstates the issue, underscoring limits of node-level censorship (source: Adam Back on X, Sep 2, 2025). According to @adam3us, the dispute centers on relay versus mempool semantics, with the takeaway that the debate is about local policy rather than consensus changes, which is consistent with Bitcoin Core’s distinction between policy and consensus (source: Adam Back on X; Bitcoin Core policy documentation). According to Bitcoin Core documentation, relay and mempool behavior are governed by local policy and feerate thresholds, meaning nodes decide which transactions to forward and keep, which in turn shapes short-term fee floors and confirmation times when demand spikes (source: Bitcoin Core policy documentation; BIP-133 feefilter). According to BIP-133, nodes advertise minimum feerates for relay, influencing which transactions propagate promptly, so traders should track fee rates, mempool backlog, and miner revenue sensitivity during relay-policy debates highlighted by @adam3us (source: BIP-133; Adam Back on X). |

Bitcoin Core Relay Rules Update Backed by @stonecoldpat0: 3 Trading Impacts for BTC Mempool Fees and Propagation
According to @stonecoldpat0, there has been no Bitcoin spam for a while and he supports Bitcoin Core updating transaction relay rules, citing context from an @ercwl talk and stating it is not 2014 anymore, implying policy modernisation is warranted for the network stack. Source: @stonecoldpat0 on X, 2025-08-28. Relay rules determine which transactions nodes relay and accept into mempools, shaping propagation and standardness policies that directly influence throughput under load and the fee market during congestion. Source: Bitcoin Core policy and relay documentation; Bitcoin.org Developer Guide (Transactions, Mempool, and Fees). For BTC traders, any relay policy change can shift mempool composition and effective minimum fee rates for timely confirmations, so monitor mempool size and median fee-rate changes around implementation windows to manage slippage and settlement risk. Source: Bitcoin.org Developer Guide on fees and confirmation dynamics; Bitcoin Core policy documentation. Tactical takeaway: if mempool backlog rises and fee-rate floors climb following relay-policy adjustments, tighten intraday risk limits on on-chain settlement, widen withdrawal-fee assumptions for arbitrage legs, and prioritize high-fee, child-pays-for-parent strategies to maintain confirmation speed.

Bitcoin (BTC) Transaction Fees Hit Lowest Since 2011: Quiet On-Chain Activity and Miner Revenue Implications for Traders
According to @rovercrc, Bitcoin transaction fees measured by the 14-day SMA have fallen to their lowest level since 2011 (source: @rovercrc). He also reports that on-chain activity is quiet, indicating subdued demand for blockspace (source: @rovercrc). Lower fees reflect reduced competition for blockspace and lower fee revenue share for miners, increasing reliance on the fixed block subsidy under Bitcoin’s fee market design (source: Bitcoin.org Developer Guide). BTC traders can monitor fee trends and mempool congestion alongside the 14-day SMA to gauge shifts in on-chain demand and potential liquidity conditions in the spot and derivatives markets (source: Bitcoin.org Developer Guide; source: @rovercrc). The source frames this backdrop as reinforcing BTC’s store-of-value narrative, with holding behavior taking precedence over transactional throughput (source: @rovercrc). |
