Hi.

I just wonder why you focusing so hard on trying to stake your old coins, instead of trying to convert the coins you have to the new ones before it will be to late/ hard to do it. If you wanted to stake you had all the time in the world before  new one was released, see the possible staked coins as gone (kinda is a reason why all others didnt wanna wait it out and stake as much as they can on the old one before they did the switch ) and focus on getting your actually coins swapped before old chain colapse would be a much better thing to put your focus on.
