Guys, is this normal?

Almost all my mined blocks are not acepted.
How can I improve my minting?
On any POS coin two things count:
1) lots of good connections. If your wallet has 8 solid connections, that increases the chance that if there's a race condition you don't lose as often. If you have been loosing with 8 connections or more, shutdown wallet, delete your peers.dat, restart and try again to get better peers.
2) Connections with the IPs that put out the most blocks. Odds are you get into race conditions with them, always loosing, because you aren't directly connected, and the peers you are connected to, don't have good connections themselves.
If there's an addnode list, you might want to add that to your conf file as well.
