Please do not send BTC to BCH and vice versa, as they are two separate currencies/protocols.
If you have mistakenly sent your BCH to your Jaxx BTC address or the other way around, there is a simple way to recover the funds and place them in the right wallet.
All you need is the Private Key of the address you mistakenly sent the funds to (e.g. if it was a Jaxx adddress: MENU > Tools > Display Private Keys > (I UNDERSTAND) > Display Bitcoin (Cash) Keys) and then go to MENU > Settings > Import Paper Wallet > Transfer Paper Wallet and use the walk-through for the coin you sent.
More specifically:
- If you sent BCH to a BTC address, get the BTC address Private Key and use the Transfer BCH Paper Wallet option to get the BCH in the Jaxx BCH Wallet you initially intended to send it to.
- If you sent BTC to a BCH address, get the BCH address Private Key and use the Transfer BTC Paper Wallet option to get the BTC in the Jaxx BTC Wallet you initially intended to send it to.
If you need more information on how the Transfer Paper Wallet option works please check this guide.
Disclaimer: Please make sure you do not share your private keys with anyone, including Jaxx support team, as if someone gains access to them, they will also be able to manage your funds.
