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.
well for me i find it easier to partially store my bitcoins on a trusted online exchanges that supports these forked coins (yobit for example) because it is then automatically adds up to your account balance and you wont do anything complicated like importing or exporting your private keys blah blah blah etc.. some bitcoin faucets are also supporting these hardfork and one of them is freebitco.in, i actually use and tried this one and i succesfully recieved my free forked coins equivalent to my current bitcoin balance on my account.
