The following guides explain how to set up the Gridcoin Research wallet client on the platform of your choice.
If you want to run Gridcoin in investor-mode only, you do not need to install the BOINC client. In this case, you will only earn POS interest and not recieve DPOR payments due to a lack of BOINC research. The amount and frequency of interest depends on the quantity of coins you are holding in your wallet/client.
If you're not interested in earning POS rewards, you can use several third party Gridcoin wallets to hold your GRC off centralized exchanges.
