As approaching the 1st of august the bitcoin community prepared to be shocked by the upcoming fork,
no one know or can predict the impact.
The main purpose of the fork is to add more supply to the current demand.
Probably to avoid ghost transaction the transfer functionality will be deprecated or disabled , hence a good preparation will be to move all you funds to a local wallet (which might result in duplication of your coins).
Alternatively you can take your coins and "reinvest" in alternative as currently the BTC position to ALT coins (like ETH/ZEC and others) is much higher then previously this will keep you aside from the implications of the fork,
Some oppose to this change and some not, the forces that work here will scale the picture of bitcoin ,
Miners , Traders, and companies operating on the chain.
only time will tell.
