Doesn't matter what will happen on 1st August - I will never sell my Bitcoins. The price will be grow for sure in the future!
Are you talking about never selling your BTC on both chains? If there really is a split one of the chains might die out and stay at purely speculative level, while the other one keeps growing. In such case it might be a good idea to sell.

I don't like this idea and I don't recommend selling your coins there. Who knows what will happen to those frozen coins, maybe they'll disappear forever
Terrible advice. This is how you lose your bitcoins. Going to be a lot of sad people on this forum one day in the near future thanks to all the disinformation and bad advice.
