According to @BitMEXResearch, Bitcoin transactions paying below 1 satoshi per vbyte do not price out legitimate payments because higher-fee transactions are prioritized for inclusion. Source: @BitMEXResearch. Bitcoin Core policy prioritizes transactions by feerate and enforces a typical minimum relay fee around 1 sat/vB, so sub-1 sat/vB traffic is generally not relayed or is deprioritized, limiting its impact on confirmation times and fee pressure for standard payments.

For traders, this indicates alleged low-fee spam should not materially elevate BTC on-chain fees or disrupt exchange deposits and withdrawals that use market-rate fees, reducing fee-driven latency risks in arbitrage and settlement workflows.

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).
