Thank you for nice explain 
If the the price would drop to 65 again for example that would be good to buy some more, and sell again at peak.

If the price drops to 65 again I think the party is over.
If that happens, wait until late on 8/22 to buy after today's bump settles in a little. Personally, I would spend no more than half of what you made in profits from today's trades. Keep your risk low.
Probably there will be another big pump on 8/23.
