This is very simple thing , you should think that lot of amount of the Bitcoin are hold by the owner of the Bitcoin , so what will happ if the network of the blockchain will face problem , I mean we don't need to worry much about this , and instead of this some preacuation should be taken by us .
1) Before 1 August transfer your all Bitcoin at the blockchain wallet .
2) If you have Bitcoin then transfer only Bitcoin to your address of blockchain also .
3) don't make transaction like things from any of the Bitcoin wallet .
4) Make backup of your wallet of the blockchain before the 1 August .
If you will do these things , then I don't think that you need to worry anything ways , because you are in official ways and platform and nothing is problem in the official wallets

If you're saying blockchain.info is some sort of "official wallet" you are sadly mistaken newbie. Maybe do a quick google to see how crappy their security is. I'd trust mt gox more than blockchain.info hahaha. This is hard to understand because your English is so crappy, but the advice is terrible so it's for the best.
Fork = one chain becomes two. You'll already own bitcoins in both. Don't worry about that. The price will go up because bitcoins will be usable for small transactions again. Finally.
