I finally managed to swap my coins:

1) download Copico wallet
2) withdraw from Cryptopia
3) make snapshots of your Copico trade history (buys and sells)
4) try to sync Copico wallet (takes a lot of time)
5) dowload and sync Caz wallet
6) join discord and send pm to CAZSAM for information about manual swap

Manual swap will end on the 7th of June. All coins swapped manually must have proof that they were in possession prior to April 15th.
