Now that you got your private key(s) for the address(es) that contained BTC prior to the fork, create that coin's wallet in coinomi - WITHOUT altering the derivation path.


3. Open that wallet and click on .../Sweep Wallet and choose the coin you want to sweep.


4. Paste or scan the BTC private key that you obtained in step 1. Your coins should now appear in your Coinomi wallet, while your BTC are still untouched. If you have any problems sweeping please consult this article.


"I swept all addresses but there are still some coins missing!"

When you send coins out, an address usually has to be emptied completely. Most wallets send the "change" back to a different address inside your wallet. On the Derivation Path section of the BIP39 file, change the "External / Internal" value from "0" to "1" to list the "change" addresses. Then find the address that has the rest of your coins and sweep it like you did with the others.


Instead of sweeping, you're also most welcome to choose a faster, more secure multicoin wallet, ending up with all your coins (BTC, other alts you might hold in other wallets, and the coins from the fork) in Coinomi. To do so, you can either normally send your Coins to newly-created Coinomi wallets for each coin, or, directly import the seed (phrase) of your current wallet into Coinomi.


To do this click on ".../Settings/Restore Wallet" and enter the seed of your current (non-Coinomi) wallet. Then create wallets in Coinomi for all the coins you held in that other wallet provider. Make sure you back up your current recovery phrase if you have any coins in Coinomi already. After you see your BTC balance in Coinomi, follow these instructions to get access to the forked coins.


Users who didn't have BTC at ALL, during the time of the snapshot, wether in Coinomi or some other wallet provider, are NOT eligible for BTG. Purchasing BTC after the snapshot and sending to Coinomi or any other provider will NOT get you BTG.
