To stake Pandemia there is no minimum limit, but it will have a higher chance to give reward with a higher amount. I think 500-1000 coins will be enough to get good amount of rate profit while staking. Is there anybody still staking Pandemia? You can share details with us.
as i know ( i asked to support team) They recommend between 300-500 up to 1000 on each splitted address. so you are telling right. 500-1000 is right amount as we have seen details. However 300 is enough too.
