That is kind of effed up though. If you have thousands of accounts you can't hold them past 4 years then or you won't 'own' them anymore.. Hmm...
Guess there will be a huge sell off when the 4 year period comes close to PASC's start.
You don't lose the accounts you only lose the coins. So just move them into one account you keep active. The accounts will stay attached to your private key forever.
