Every IMO (Initial Masternode Offering) has a pre-defined CAP. The cap is the total amount of funding needed to setup a Masternode.
When an IMO turns out to be cheaper than originally anticipated, Goldnode.io will pay back whatever leftovers we have according to your share in the Shared Managed Masternode. This will also be communicated through your personal Goldnode dashboard.
Price are dynamic and changes every hour to adjust to the eventual volatility of the coin.
