Hi, developer!
  I just now discovered that there was a renewal of the Grim. How can I exchange my old coins for new ones? Perhaps it is already impossible, if you wrote that only 12 days are given for swapping. If 100% is impossible, then this is not correct. It was necessary to do so that even after a year a person could exchange old coins for new ones. Whether it is not enough that can be.
So, now can I send the coins to the dustbin? I am disappointed. You not only deleted the POS, but also made 4 times less coins, so even after 1-6 months it is now impossible to exchange old coins. More flaws. And I did not see any pluses.
