Hi mate. Masternode is POS (Proof of Stake) Which generally generates more passive income (interest) than staking alone. It requires a preset amount of coins. Dash 1,000, EXCL 5,000 and of course PIVX 10,000. One of our top developers is meeting with me online in a few hours to discuss utxo (another type of passive income) and to show me a few things from a technical point of view. Hopefully, I can get a few videos out explaining everything soon.
Cheers,
Fish
