Why there is no any payments to MN now? Last payments were 2 days ago. Is this a bug or done for a specific purpose?
There has been MN payments. Payments have been received yesterday and today.
There are 15 enabled Masternodes in the network at the moment. But no one gets reward. Block explorer shows that last 100 block rewards got only miners. Why?
Some masternode owners have hot/cold wallet masternode setups.
What means "hot/cold wallet masternode setups"?
Hot wallet is the MasterNode wallet on the VPS or any other remote machine. It has no coin, the balance is 0 and need to run 24/7
The cold wallet is your local wallet, this one is holding all the coins. You lock the 1000 VIVO into this wallet using one of it's account addresses where you send the 1000 exactly. You will receive all the reward into this wallet too. The cold wallet doesn't need to run 24/7, it doesn't need to run at all.
