What can work in situations like this is to change the staking percentage to something lower.   Stackbit and 1337/EliteCoin both did that and it worked.  You have bagholders of early adopters who want the coin to succeed.  You put some utility into the coin to give it a reason to live.  Looks like XP already has that, just needs to create a new wallet with something like 15% staking so people still have a reason to use the wallet.  Staking for good returns is going to get more and more popular.
