PART - Particl is a good PoS(v3+) for passive income. Plus being a token holder makes you a governor on the platform. The dev team has some things in the works that other teams don't and that will give stakers more income.

1. A decentralized private marketplace. Roadmap
   -- Sellers pay fees to list which goes to stakers. Extra income on top of block transaction rewards.
   -- PART owners govern the direction of the platform, can vote on item listings deemed "illegal"
   -- PART is the fuel on the marketplace. Any coin will be able to be used but it's shifted into PART to complete the transaction.
2. Cold Staking. Currently on Testnet6
   -- More secure than "unlock for staking"
   -- Works with multi-sig to allow single node to be a cold staking wallet and another node to be able to spend the coins.

The #particl platform is really decentralized too if you look at the extraction numbers on CryptoID explorer: https://chainz.cryptoid.info/part/#!extraction
I mean, look at that pie chart!
