There should be at least the statement that generally, PoS alt-coins (programs) automatically do PoS "work" when the program starts.  The only proviso is that you have to have some units (coins) in that crypto-currency (coin).  And the best way is to earn them by doing something useful for that currency (coin). 

The terminology used is so deceptive , wrong and misleading in this whole arena that it is really difficult to answer simple questions without having to define - explain almost every term used in answering the question!  See https://www.youtube.com/watch?v=Ur037LYsb8M especially about 12 minutes in.
