I have some questions about PoS. So if I understand it correctly, I will get 1% of any coins that stay in the wallet for 30 days or more, is this correct?
Does the wallet need to be running for 30 days for it to work?
It's 1.5% per year. So get that amount and divide by 12 months if you want an estimate of your PoS coins per month, also assuming you don't move or use those coins and let them sit there. Your wallet needs to be online at least a few hours per day, with or without a password (depends on some configuration.)
