The first of August, 2017 will be the target day in activating the segwit that is intended to come some issues faced by Bitcoin currently. The non-technical Bitcoin users does not really understand the segwit, thus, making then con, pro, or neutral towards its activation. No body is certain if the price will go up or down when the activation come. In my opinion, it is much probable that the price will go up after the activation. Because I believe that the proposal of segwit is for the betterment of Bitcoin.
