Lost wallet.dat

Hi there, is there any way to recover a wallet when wallet.dat is lost?

Regards

If you don’t have a backup of your wallet file (or a dumpfile of your keys which is risky), than you are out of luck.
Are you sure it’s gone? How did you lose it?
Sure it’s not only in the wrong directory? Did you check if you have a data directory named syscoincore (the name used in a previous version) instead of syscoin?
