According to Samson Mow (@Excellion), Bitcoin Core has officially announced that they will remove the OP_RETURN limit in their upcoming release, sparking significant debate among traders and developers. This technical change will allow larger arbitrary data storage on-chain, raising concerns about increased blockchain bloat, higher transaction fees, and potential spam attacks, which could impact Bitcoin's transaction efficiency and trading liquidity (source: Samson Mow, Twitter, May 5, 2025). Traders should closely monitor mempool congestion and fee dynamics as these could influence short-term Bitcoin price volatility. Users who prefer stability are advised to remain on version 29.0 or migrate to alternative implementations like Bitcoin Knots, as highlighted by Mow. This policy shift could also affect altcoins and token projects that rely on Bitcoin for data anchoring, potentially altering cross-chain trading strategies.
