What are the costs to maintain a masternode?

It depends on the onboarding mode you select:

• If you select the Simple Onboarding, your node will be hosted on one of the servers provided by our masternode management partner. These servers are strategically distributed around the world at differet hosting providers to provide security and quick speed. By selecting Simple Onboarding, you also don’t need to work with the setup of your node, it is installed automatically. In this case, you don’t have any cost with the node.
• If you select Normal onboarding, you need to rent a Virtual Private Server at a hosting provider, and you need to install and set up the node. In this case, you need to pay the VPS’s monthly fee for your hosting provider.
