My advice and opinion for August 1st:

There will be split/fork of BTC and BCC(Bitcoin Cash) will come. Now also many traders do not know what is going to happen and what they should do in this situation. They are thinking upto 21st july it was clear that there will be no spliting after successful lock in of BIP91 but again suddenly what is this news of spliting ?
This is created by very less number of miners those who are in support of BCC.
BCC is now available only with Viabtc and price is approx.. 400$
Many exchanges disagree to list BCC at present and some will list.
If you have BTC and u will keep it in your offline wallet with your private key than you will get same number of BCC absolutely free
For example if u have 2 BTC in your offline wallet then you will get 2 BCC free.
But problem is that many traders do not have offline wallet and if you will keep your BTC with any third party exchanges like POLONIEX BITTREX then it depends on them whether they will give you free BCC or not. But keeping BTC at exchange at the time of fork is not wise.
As per us price of BCC will come down very fast .. why ?
At present it is listing with only Viabtc when it will list to other exchanges and people will get BCC in free then maximum will sell it so as a result there will be huge sell orders compare to buy orders which results in price fall.
Now what should we do ?

1. If u have offline wallet with private key than shift your BTC and enjoy free BCC
2. Those who do not have offline wallet they can convert it to USDT bcoz in this whole drama BTC price may come down and with USDT we will be safe from that loss. And 1st Aug split tension will be zero bcoz we dont have BTC in exchange.
3. Avoid BTC transaction little bit before and after 1st Aug. If you have buy bids( if it will not complete than your BTC will be there in exchange) & sell bids (after complete you will get BTC) than cancel all those orders and shift your BTC.
