On October 20, 2017, Coinbase published a document titled Bitcoin Gold FAQ . This document contained the following statements:

At this time, Coinbase cannot support Bitcoin Gold because its developers have not made the code available to the public for review. This is a major security risk.


When will this fork occur?
The fork has already privately occurred at a point known only to the Bitcoin Gold development team. The Bitcoin Gold blockchain will be made publicly available when the Bitcoin blockchain reaches block number 491,407, which is currently estimated to occur on October 25, 2017.

Bitcoin Gold is a community-driven, open source hard fork of Bitcoin, and as such, all of the code is available on our GitHub repository for review by everyone, and it has been since the day this project was initiated. Here is a snippet from the blockchain configuration file:

The above marked code means that the new Bitcoin Gold consensus rules do not come into effect until BTC block 491407, which has not yet occurred.

The Bitcoin Gold development team has been working an average of 16 hours per day over the past week to provide a secure and stable implementation of Equihash proof-of-work algorithm on Bitcoin, and we do not welcome this kind of speculation regarding our product.

We kindly request that Coinbase review their statement and edit it in a way that is based only on facts, not assumptions.
