Well, I am not worried by now because:
1. Most coins have lost > 60% of its value since January 5, so PAC also would lost value even without the 1000 to 1 change.
2. To reduce the supply of old PAC by 1000 seems necessary, it will make easier to enter in other change-houses and also trade with BTC.
3. I sent yesterday a lot of old PAC and received the new PAC in about 12 hours, it is not instantly, so no necessary to panic if it takes 24-48 4. I recommend to change the old PAc in 2-3steps, no all coins at the same time, this will down ansiety while waiting to receive the new coins.
5. New wallet is good, very much quicker and lighter.
I hope this all will help to improve PAC value with time, just be patient and see what happens.
