Yes there are more BTC hard fork coming and it begins I think this 12th of December and it's SuperBitcoin I supposed. I don't know the exact date of it but many forks will be made this December. I don't advice that you could keep your BTC's on an exchange because some of them don't give your free coins bu somehow in Bittrex I experienced on the first hardfork I received BCH after a day or two before the fork. I advice you now keep your coins on your own cold storage wallets or somewhere safe.
