The most expected,and maybe most important day for BTC is today. What are you expecting is going to happen post 1st Aug?
I think that bitcoin is less likely to have any changes. The bitcoin price might go down for some time after the fork but most probably it will bounce back and even pass the highest value that it has reached before within a couple of months or so. I sure hope that the transaction confirmations would be faster and with a minimal fee. As of now, bitcoin cash won't have much impact but I guess sooner or later we will be able to see the opportunities enclosed with it.
