At the moment it is slightly complicated, specially if you are new to crypto. You would have to use another exchange to convert eGold to another crypto that you can then convert to your currency. I personally use euros and use binance to exchange eGold to USDT and then coinbase to convert USDT to EUR.
https://www.coingecko.com/en/coins/elrond#markets lists all market pairs for eGold so you can choose platform best suited for your location in the world.
But we are in the beginning of eGold and crypto in general so if possible consider not selling ;)
