If you accidentally sent your BCH to a Bitcoin legacy address (No SegWit), you can try a recover.

Remember: the Bitcoin destination address MUST start with "1".

Here below the steps:

1. First of all take note of the Master Private Key of the BCH wallet to which you sent the BTC.
Open Edge, wallets list, click on the 3 vertical dots on the right of your BCH wallet, click Master Private Key and copy those words one by one on a notepad (you cannot copy them directly).

WARNING: Exposing your private keys can be risky if you do not take the right precautions. Using a private browser or opening the derivation tool on an air-gapped PC will help prevent malicious software from stealing your keys. Most users will not need to follow these steps and they are presented for informational use only. Remember to close the notepad once done.

2. Now you need to derive the individual private keys: we recommend using Ian Coleman's tool https://iancoleman.io/bip39/. All bitcoin-related currencies in Edge can be derived using this tool.

Generally, the process to derive private keys is the same for each currency and involves these three steps:
-Enter private seed (24 word phrase) into the "BIP39 Mnemonic" field
-Change the Coin
-Select a derivation path <-- This step may be different depending on the coin and which type of address you are attempting to derive a private key for.

In your case choose Bitcoin (NO SegWit) Bip 44 m/44'/0'/0'/0.

Look down and search for the address you accidentally sent BTC to. When you find it, on the right you'll see the its private key.

3. Open Edge, go to Menu, Sweep Private Key, past that private key or scan the QR Code, select Import and wait for the funds to be transferred into your BTC wallet.
