How to Buy Polkadot (DOT) with NinjaRoll (ROLL)

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