Ok.I can solved this ploblem. I delete all node in GalaxyCash.conf except addnode=193.124.0.135 .
But i lost 3000+ gch .

You can lose coins only in one case, if you delete wallet.dat.
Coins themselves do not disappear from network. This is not a Hogwarts network.
before I delete every file (except wallet.dat) i have 4800 gch
now i have 1800 gch.

I think because my pc add another node?
