Just popping in quickly, can anyone tell me if there is a masternode payment for each block or if, for some reason, only some of the blocks give masternode payments? It makes a huge difference in the amount we can predict on getting paid.
There's a masternode payment each block, it's always 10% and randomly selected. You can also see masternode stats (and payments) here:
