Investing on Dash is expensive nowdays.
On some old coins it is either expensive to setup a masternode or even to get 10k minimum coins for just staking can be damn expensive.
What are your top 3 Staking coins for the future that might give you ROI such as Dash?
My bets are:
1. NEM
2. NXT/ARDR
3. ReddCoin
Opinions about GridCoin/Ark/PIVX?
SpectreCoin has Proof of Staking, and there's no minimum required. The larger the amount you're staking with the more likely it is you'll receive a stake reward (about 5% of the total amount of XSPEC per year, if I remember correctly). It's a great privacy coin and is grossly undervalued compared to other privacy coins, especially once you account for the high quality privacy technology in XSPEC. In an upcoming update stake rewards will given using stealth addresses, making staking even more private.
