How to Buy Polkadot (DOT) with Sharp Portfolio Index (SPI)

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