Use FiatDex

FiatDex is a relatively new service ran on a trustless Ethereum smart contract that allows for two people to swap crypto for fiat without needing a 3rd party. This means no more middle-men and no more having to give out personal information to an arbitrator in cases of disputes. Instead, users work together to fulfill the terms of the agreement between each other. Using mutual collateral, both traders are incentivized to complete the trade otherwise they risk losing some of that collateral.

Due to a collateral requirement, both users need to have cryptocurrency initially, so it is not for those who are completely new to crypto but rather for those seeking to get more or cash out.
