I received NAVS today, from staking, about 2 days worth, before that it was very slow, and even couple of transactions that didn't go through.
IMHO nothing is wrong, just big volume of NAVS being sold and bought, so it takes couple of days. In the long run you should get 5% exactly, nothing more nothing less, so calculate it for yourself.
If the percentage was much higher than 5% for some time, you will receive nothing for couple days.
I am not sure its that works.
many coins not staking or on markets or in offline wallets. So if someone have big fat wallet and staking 24/7 I think he has good strenght weight so can stake more profitable than this 5% on year because he staking when others not staking so he can get more than 5% ? Or what if make stake who give 5% in this year (max) number coins so he stop taking new coins because he limited max 5% ? I dont know its is possible stop taking coins from pos in thats situations when many wallets no stake and someone stake 24/7. My wallet working and I stake everyday last days but I remember I was staked many more few weeks ago. Now i stake 30% on day my usually stake.
