Masternoding is NOT mining. It's NOT trading too!
It is an alternate way to earn revenue is by providing technology (a master node) that relies on a proof-of-stake (PoS) approach.
A master node, like any other full node, is a node server within a network, and full nodes are important because they process transactions and store them in the blockchain.
However, a master node operator has rights beyond those of a normal full node operator, and is required to manage more critical tasks – bringing the operator higher rewards.
In order to obtain the status of a master node, the master node operator must deposit a specified number of the relevant coin. For this “staking”, along with performance of
the required tasks and the provision of computing power plus storage space, the operator receives rewards based on the corresponding coin (proof-of-stake).
By operating appropriate master nodes diligently whilst constantly monitoring and optimizing with clever strategies, extraordinary profits can be realized.
