I checked. The both were POS. I will wait MN coming.
No, if your wallet is on Masternode, then all your coins will not be staked. Because you have to put "staking=0" in the sagacoin.conf.
And if your wallet with only 2500 SAGA, then 7.535 should not be your PoS stakes, because you should get 1+ SAGA per day only with staking from 2500 SAGA. <== Ignore this sentence if you are confused, anyway Masternode wallet will NOT be staked.
EDIT: Conclusion : 7.535 should be your first MN reward.
OK. So I now earned 14.07 SAGA in 33 hours from master node, not POS.
Dashborard spendable is real, and transactions are bug, I think.
It seems less than masternode.pro says 44.24 saga per day.
https://masternodes.pro/stats/sagaHopefully it is going increase.
Thank you very much for your honest and warm support.
