How to Purchase Polkadot (DOT) using Altair (AIR)

To buy Polkadot using Altair, first, find a cryptocurrency exchange that supports the DOT/AIR trading pair. Create an account, verify your identity, and deposit your AIR into your exchange wallet. Locate the DOT/AIR pair on the trading platform and place an order to exchange your Altair for Polkadot. If the DOT/AIR pair is unavailable, you can first exchange Altair 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. In Germany, it’s also important to consider the tax implications of your trades, as capital gains tax may apply to your profits from cryptocurrency transactions.
