The right time to buy

I got a second job this summer, and my plan was to invest all my earnings form that job into crypto currencies. But with all the talks and panic being hyped up around August 1st, I was thinking about waiting until then. My prediction is everything will fall heavy in that first week before they pick back up.

I want to profit from the panic sellers who's hands are not steady and will ultimately call it quits. I have been buying ethereum non stop for the past 2 months, but unfortunately I bought the most at the $350 mark. And I'm going to keep buying eth, because I truly believe in it.

But my question today is for all the smaller coins (steem, antshares, stratis, etc) what do you think will happen to them? Should I buy them right now since I can? Or will they crash after August 1st, and I can buy a whole lot more? I personally don't think anything should happen to the alt coins, but since the whole market moves with btc currently, I truly think they'll be affected
