“VC coins” are crypto projects with tokens that raised money from private investors rather than doing public ICOs.
Orchid is a privacy software service with its main feature being a decentralized VPN service. Its token is OXT.
OXT is used by users to purchase VPN service. Orchid node providers receive OXT in exchange for their bandwidth.
Both Orchid users and providers can stake OXT.
Coinbase has launched Orchid (OXT), and you can learn about OXT and earn some OXT in the process via Coinbase Earn.
