ive found some POS blocks but it doesnt added to my balance, is it only me?
If you're talking about the 50XPH blocks I'd suggest you actually read this thread.
i havent read the thread,is it scam then?
PoS is 15% yearly

15%/365d/12*=0.00342% for each PoS block
* min PoS age is 2h, 24/2=12
Masternode gets 50XPH + 20% from Pos Block(that's doesn't matter)
Unique reward structure
Conclusion: You need to run a masternode
Yep I just got my masternode up and receiving payments so they work.
