Hello,
If you bought some OHM and intend to hold it medium term then you should definitely have it be staked in the form of gOHM. In the image below are the difference between the different tokens in one graphic. You can read more in our docs: https://docs.olympusdao.finance/main/contracts/tokens
A note: We have scammers preying on new people by posting fake links on this forum to steal from people (please do not click any link to chat with "support", "live chat" or whatever link is posted). As a result, this forum is only used for governance, not for support anymore. Please come on discord and ask in #questions, you WILL get an answer there.
Do not trust anyone pretending to be support or whatever contacting to "help" you, they are trying to steal from you.
