I think the panic will not stop until after august 1st.... I expecting some price drop within this period. Hope for the best.
The best will be if you are to buy at the time the price drops, and the panic sell will continue to drop till after the day of segwit.
Segwit is already locking in today, thats why the price has risen so much. The next potential panic will start when they attempt the hardfork to 2 mb blocks in 3-6 months.
