Selling BIP-110 Fork Coins Could Trigger Replay Attacks on Bitcoin, Developer Warns

The Bitcoin network is bracing for a potential minority chain fork this weekend, and the immediate risk isn’t just about price volatility—it’s about users accidentally draining their own wallets.

A developer warning circulating ahead of the expected BIP-110 split makes clear that selling forked coins could inadvertently authorize transactions on the original Bitcoin chain, resulting in permanent loss of real BTC.

The safest course, as outlined in the original report, is to do nothing until the chains are properly separated.

Unlike previous high-profile forks such as Bitcoin Cash, which shipped with strong replay protection, this minority chain apparently inherits Bitcoin’s transaction format without any mechanism to distinguish new chain operations from legacy ones.
