Hey! Zerocoin advise you to do pre-fork before wallet maintenance on exchange,please transfer you zerocoin to your wallet!
I have done that just now,but have some troubles while I was setting up my wallet. I will share you here how I dealt with them.
First you should go to their homepage(https://zerocurrency.io/) to download a wallet that fit your system. then open it...problems may come here. What I saw was this error
Don't worry, check the answer from dev
Next when you open it again,it may freeze at there
OK! check you firewall if it blocked zerowallet,actually I closed my firewall and it fixed!
Wallet opened and begin to do synchronization,I saw it began from year 2017...and thought it must take me lots of time,so I simply thought I should download bootstrap from their homepage.At the same place you download bootstrap you will see a txt file, it is guide for you.When you follow their direction do you have trouble like it doesn't work and synchronization again began from year 2017?Try to delete .dat files in "block" file(appdate-->roaming-->zero) and open again.Failed ? don't worry man,just re-install it and give-up bootstrap,wait until the synchronization done form year 2017, you will find it doesn't take you much time at all lol,1 hour or so.
And, if you have such problem
1.close your wallet
2.re-open it
3.do 1 and 2 again and again until it fixed (answer from me)
Finally all issues fixed?Don't forget to export your private keys!
Good luck guys!
