First of all there is nothing to get worry about it until it happens, don't think make your own scenario of it and it makes you worry of it. Aug 1 is tomorrow, what we can do is just wait until it happens, no point of worrying of something that your not sure of what will happen. I myself don't even think about it but when the time comes, that's when you take your action. You don't need to split your BCC from BTC it totally depends on you if there will be no split but if there will be a split, what would I do is just keep for it, and see if the price of BCC will pump or dump. What we can do now is just hope for the best and Good luck to everyone.
