How is ROI calculated?
The ROI of a masternode is calculated as the quotient of the masternode reward per node and the cost of starting a masternode multiplied by 100.
If the ROI is 100 percent, the money invested will bring the same amount for the year. If 200 percent - double the volume. The indicator can be tens of thousands of percent. This usually happens with the so-called shitcoins, little-known unreliable projects.
In theory, the number of masternodes should always grow, and the ROI should fall. In fact, this is not the case. Sooner or later, a decline in return on investment will force some impatient owners to quit the game and close the masternode. In this case, the remuneration for masternode holders will increase. The self-regulation principle is the same as in mining.
