Obviously not. BIP91 activation has already been confirmed. The lowest price you will see for Bitcoin in a loooong time will be today.
I concur with you. In the current scenario, it is out of questions that bitcoins will face any other dump before August 1st. All coins will move farther in the green area of the graph. Segwit will drastically pump up the values of coins further. Before August 1st, its a great opportunity for those to grab bitcoins again who gave up on their coins in few last months enjoying a ride to moon.
