How to Purchase Polkadot (DOT) with Green Block (GBT)

To buy Polkadot using Green Block, first, find a cryptocurrency exchange that supports the DOT/GBT trading pair. Create an account, verify your identity, and deposit your GBT into your exchange wallet. Locate the DOT/GBT pair on the trading platform and place an order to exchange your Green Block for Polkadot. If the DOT/GBT pair is unavailable, you can first exchange Green Block 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.
