After August 1, nothing wrong with bitcoin will not. Too many people have bitcoins and they're not interested in losing their coins. It would be too stupid to destroy the thing that took so long to build by millions of people. I recommend a few days to refrain from carrying out transactions until things get better.

Paper wallet is ALWAYS recommended to store your Bitcoins, no matter when, why or who. lol

The bottom line is, a paper wallet is 100% anonymous and also just like cash. You must make sure not to lose it otherwise you are in for a really bad day... hahaha.

I have heard a theory that after the 1st August bitcoin is going to be shared on real bitcoin and something like a copy. And people say that real bitcoin will be on Blockchain.info wallet. I don't know is it truth or not. But I don't store my coins, so, I kinda don't care.

Paper wallet is a good option in case of split, you will can use that keys on both blockchains

Thank you all for your comments!

I will keep my Bitcoins as long as possible and do not spend them. I hope in 10 years they will be much more worth.
I will let them on the paper wallets and wait whta happens in the future

As long as you control your private keys, then you are fine. I wont trust some exchanges in honoring the coins Im entitled from the split chain. Judging from what happened in the ETH and ETC split, BTCe didnt give their customers any ETC and who knows what they did with them.

Coinbase also didnt give their users any ETC but at least the CEO admitted that they had made a mistake.

I would expect some of the exchanges to issue some kind of statement to let users know where they stand in the case of separate chains, Bittrex were good the last time around with ETH and ETC but not all exchanges as you said were interested in doing the right thing.

I would expect the same thing to happen. Your coins would probably split to both new chains.

But I would use either a hardware or offline wallet. For the hardware wallet, try companies like Trezor or the Ledger Nano S. Both corporations are setting up servers which would allow you to spend on more than one chain if there is a split.

For offline wallet, I’d suggest something like Electrum, or literally any wallet that does not have access to your private keys. As long as you have 100% access to your private keys, you should be fine. As the saying goes ‘if you don’t own your private keys then you don’t own the coins’.

One thing to abstain from doing is storing anything on an online wallet such as Coinbase or any exchange, like Poloniex. History has shown such a course of action to be an unfavourable one.

1st August isn't the set date for a chain split to happen. What will happen on that day though is the UASF, which won't result in a chain split but may or may not indirectly contribute to activation of hard forks.

As long as you have the private key of the bitcoin wallet you store coins on then you're fine. If you have your coin on an exchange then i suggest you send these coins into either a hardware or paper wallet. Blockchain.info would work fine too although they may only support one chain after the potential chain split meaning atht you'd have to import your private key elsewhere to gain access to the other coins.
