With Proof of stake coins, sometimes you can profit more by staking as opposed to masternode set rewards (I know, but it is how they are designed)

So if you invest in a staking / Masternode coin, do check the network MN / Staking linear scale, anything of 50% sway one way, and you could do well.

Of course with staking the more coin you hold on the network with accrued active time, the more of a chance of a stake or reward - the networks will always adapt / change difficulty etc but as long as you are taking part (and the wallet is unlocked for staking) you are in with a chance of a reward.

Keep on staking!
