Take as large a position as you possibly can, initially, and the early staking rewards are astonishing (see the STEEP HILLS system).  To control dilution, however, they diminish later on. 

Plus, you are staking an awesome coin -- screaming fast transactions, hardcore anonymity features, a dedicated and responsive team, a great community, and a roadmap that will make them the coin of choice for privacy fanatics.
