Update 8/28: Airbitz (the technology behind the Athena Bitcoin app) is likely to support at least the sending of Bitcoin Cash (BCH) from the wallet interface in a future release. While we have no idea when this will occur, we would recommend that most Athena and Airbitz users now wait for that future version as a much easier way of accessing your BCH. To access your BCH before that update, see below....
Athena Bitcoin app and Airbitz app users are encouraged to read the guide linked below from our technology provider, Airbitz.co. Other wallet users will want to contact their wallet provider or consult this handy guide from Coinomi. Be warned that no matter which wallet you use, this is an involved and technical process. Please read through the instructions, first, and then follow them line by line very carefully:
Option 2: Using the Coinomi app to acquire your Bitcoin Cash
In addition to the Electron Cash wallet used in the above guide, which is primarily a desktop wallet, testing here at Athena has revealed that you can also use the Coinomi app to access your Bitcoin Cash. Coinomi is a multicurrency wallet you can run on Android mobile phones alongside your Athena Bitcoin app. Using Coinomi, you could have your Bitcoin and Bitcoin Cash in two separate wallets on the same Android device. Here's how to do it:
- First, follow the Airbitz guide above through all parts of Step I and Step II. Most likely you'll need to access the Airbitz Recovery link using the web browser on your phone and switch between that and the Coinomi app. By this point you should have already swept all your Bitcoin (BTC) to a new wallet within your Athena app and see that transaction inside both wallets.
- Download and install the Coinomi app from the Google Play Store. You'll need to write down the recovery phrase on a piece of paper and store that securely (just like your Athena user/pass). Type in a password for the wallet.
- Select "BitcoinCash" from the list of coins presented to you and press Finish. Agree to the terms.
- Go to your new Bitcoin Cash wallet and tap on the three dots in the top-right corner of the screen. Select "Sweep wallet" from the resulting menu.
- You're at the point where you need to paste in your first private key from the Airbitz recovery page. Remember, you're looking for addresses on the recovery page that match those on the list under "Source" in the Advanced details of the transaction you just made in Step I (see Step I, part 10 of the Airbitz instructions for a visual example).
- Find your first matching address on the recovery page and click the button to the right to show the private key for that address. Copy that private key.
- Switch back to the Coinomi app and paste that private key into the field on the Sweep paper wallet screen. Tap Next. It should show the Bitcoin Cash balance of that address. If it doesn't detect any funds, go back to the Airbitz recovery page and make sure you are copying the private key from the correct address (matching one of the "Source" addresses from the Step I transaction).
- If Coinomi finds a Bitcoin Cash balance go ahead and proceed to sweep that into your new Bitcoin Cash wallet. This will take possibly several hours to confirm on the Bitcoin Cash network. In the mean time you may repeat instructions 4-8 for every remaining address showing under "Source" of the sweep transaction you created in Step I. When you are finished you should have an amount of Bitcoin Cash coins equal to the number of bitcoins you had as of August 1st.
