May I know how many PIVX coins do I need to setup a masternode and how much is the POS rate?

Did you try to look at the opening post of this topic? There's a link:
https://pivxmasternode.orgUps, I didn't saw the website link on the OP post..silly me

For anyone else, you need 10k PIVXs to be a masternode, well nothing for me then, atleast I got 100 coins at cheap price a while ago.

Also, POS rate is arround 4.8% year, but it's random.
