With 1st of August a hard fork of Bitcoin will be released - Bitcoin Cash.

There is written already a lot about it so we refer to some of those articles [1], [2] for those who are not familiar with the matter.

TL;DR:

Bisq will not add BCC as altcoin.

If you want to move your Bitcoins from your Bisq wallet to a BCC wallet you can view all the private keys of the wallet by opening the wallet details popup with alt+j. If you have a BCC wallet which supports BIP 44 you can use the seed words for importing, otherwise you need to import the private keys.

Why we decided to not list BCC as altcoin?

We have initially considered to add BCC as altcoin but we decided not to do it for various reasons.

As posted [3] a few days ago there are a few major concerns with BCC:

Risk for users privacy and lowering Bitcoins fungibility by a large-scale coin merge in case many Bitcoin users would engage in BCC exchange (moving and merging previously not connected funds).

and by a large-scale coin merge in case many Bitcoin users would engage in BCC exchange (moving and merging previously not connected funds). Setting a precedence for that model to fork off the Bitcoin network with an Altcoin (do we want to see that every month now?)

for that model to fork off the Bitcoin network with an Altcoin (do we want to see that every month now?) Lack of trust in their technically ability to provide a secure replay protection

Beside that they acted highly unprofessional in several areas:

They used the PoS of Bitstamp and have forgotten to change the name Bitstamp in the text. How hard is it to do a find&replace?

The BCC ticker symbol is already taken by Bitconnect [4] as well by a future on Bitfinex for Bitcoin Core. How hard is it to do that basic search for existing ticker symbols?

We also consider their activities unethical:

They engaged in trade mark infringement by using the Electrum Logo and make people think Electrum is supporting BCC.

They use the brand “Bitcoin” in their name “Bitcoin Cash” which might provoke confusion for users who are not so familiar with the recent activities. We see that as an attempt of hijacking an established brand.

Furthermore we have basic requirements for adding an altcoin and those have not been fulfilled:

The Coin operators need to make the request

They have to provide a pull request for the address validation

and more…

Finally it would take precious time to test a new release and do the deployment. Time we consider better invested in other work.
