There is a high likelihood that the Bitcoin Segwit2x hard fork that is occurring mid November 2017 will result in two (perhaps three) distinct bitcoin chains.

We, the CoinBase user community, are asking Coinbase, Inc to do right by their customers by making it clear as soon as possible how they intend to handle this fork, and the resulting chains.  

What is being planned for user funds? For ticker symbols? How will user funds be secured? Will we have access to our bitcoin on all chains, or will Coinbase choose one for us? If so, what criteria will Coinbase use to determine which chain to honor?
