Things I would like to know before had setting up my masternodes.
1st - Your internet provider usually give you a single dynamic public IP, they are not fitted for run masternodes. In my case they refused to provide a fix IP. So the only solution was going after a VPS.
2nd - After setting up the masternodes starting them for the button on the wallet gave me the following message: Invalid IP address. However starting them through the debugging console works just fine.
3rd- Rewards take 5 days to show up.
4th- For real newbies like me, to execute the pivxd on the terminal you have to type ./ before the file name.
