How to Buy Polkadot (DOT) with HashKey Platform Token (HSK)

To buy Polkadot using HashKey Platform Token, first, find a cryptocurrency exchange that supports the DOT/HSK trading pair. Create an account, verify your identity, and deposit your HSK into your exchange wallet. Locate the DOT/HSK pair on the trading platform and place an order to exchange your HashKey Platform Token for Polkadot. If the DOT/HSK pair is unavailable, you can first exchange HashKey Platform Token for a stablecoin like Tether (USDT) or a fiat currency, then trade that for Polkadot. Be mindful of potential exchange fees, which vary by platform and can affect the total cost of your transaction.
