In the last weeks, we had so many rumors, and because of that we had " Crash"? No, I believe its some sort of market correction, it is good for ICOs, to have more money going in instead of BTC.
Well, China's ICO ban caused price to go down, then JP Morgan said bitcoin is fraud and probably some people are panic selling bitcoins.
To be honest i see all this as simple correction, nothing more, just remember what happened week or two before August 1st, bitcoin dropped its value from 2800$ to 1800$ and raised to 4800$.
