How to Sell Tezos (XTZ) for Ethereum (ETH) in Portugal

To sell Tezos for Ethereum in Portugal, first, find a cryptocurrency exchange that supports the XTZ/ETH trading pair. Create an account, verify your identity, and deposit your XTZ into your exchange wallet. Locate the XTZ/ETH pair on the trading platform and place a sell order to exchange your Tezos for Ethereum. If the XTZ/ETH pair is unavailable, you can first sell Tezos for a stablecoin like Tether (USDT) or a fiat currency such as the Euro, then trade that for Ethereum. Be mindful of potential exchange fees, which vary by platform and can affect the total amount you receive.
