There's lots of money to be made in Bitcoin
Yes the wise choice right now is to hold your bitcoin in address which is under your full control so that you can get coins in both chain. You can dump the forked coin when it will split which will be just free money for you and when it will start to dump hard bitcoin price will certainly go up.
I think by now, everyone should be settled. There are tons of advise here regarding securing your coins. We will have a long 2 days 10 hours before the actual event unfolded in Aug 1. The price is still going strong at the moment, so no need to panic. Others may hold bcc, but I believed majority will dumped at as well. Because no one wants to hold a altcoin, specially a altcoin trying to disrupt bitcoin dominance.
