Hello everyone
I've heard and read some good things about NAV in the last 2 days, and I also heard that making stacks is gaining.
You can explain me how and how much you earn for year. 1174 pages are really too many

Is the portfolio always open?
Thank you
Yes you need wallet open to stake.
You earn 5% per year. Slightly more if you account for compounding.
Judging from my own experience as a long time holder of significant amounts (100000+) I'd say the staking gains are quite accurate
