You have nothing to worry about. There's nothing to worry about. Just make sure your coins are in awallet that gives you access to private keys. Do not leave your coins in an exchange. Noone knows how the market will react, we are not see the future. Forks happen, just keep calm and relax.
Yes seriously. People freak out so much over forks. Remember how much hype the first one created? Maybe the price will crash and we will soon benefit from their stupidity.
I think from now on we will be seeing new coins with every fork. Btw yobit support the fork coins so you can keep your BTC there if you want. I had some left over from trades during the last fork so I got them early. It is safer to keep them yourself though.
