How to Sell Cartesi (CTSI) for Ethereum (ETH) in Portugal

To sell Cartesi for Ethereum in Portugal, first, find a cryptocurrency exchange that supports the CTSI/ETH trading pair. Create an account, verify your identity, and deposit your CTSI into your exchange wallet. Locate the CTSI/ETH pair on the trading platform and place a sell order to exchange your Cartesi for Ethereum. If the CTSI/ETH pair is unavailable, you can first sell Cartesi for a stablecoin like Tether (USDT) or a fiat currency such as the Euro, then trade that for Ethereum.
