POKT is available to purchase on multiple global exchanges. Follow this DAO proposal for updates on official listings.
Note that you can’t stake POKT from exchanges. To stake your POKT you would need to withdraw to your wallet (see below).
Over-the-Counter (OTC) trading desks are white-label markets operated by trusted intermediaries who match buyers and sellers. They are typically used for large volume trades.
The POKT community has a number of OTC desks which can be found here.
Transfer POKT to Your Wallet
To receive POKT, you must use your Address, not your Public Key. The Public Key is used for API transactions, not basic wallet actions.
