roughly...
btc- wave 1 sept 1st - $4950 - $3900 on sept 4th
wave 2 - 7th sep $4700 - $3700 on sep 13th
wave 3 ......( im guessing ...14th sep $3900 - $2800 on 15-16 sep)
Yes, that's my thought as well. My more specific feeling is that BTC will be going down around $2000-2600 (but definitely agree with your $2800 number), even a short dip into $1900 and then back up again. BCH (and other coins) will most likely be dragged way down too so buckle up for a bumpy ride!
I could see BCH down around $350, even dip down to $290 a short while then boom back up again... but we'll see.
Not sure about the timing, however.
Edit: I have sold everything right now and sitting on the side lines. Will try to get back into BCH somewhere around $400-$450 and BTC definitely somewhere below $3000.
Of course...
