Bisq is an open-source digital exchange, which allows you to buy and sell bitcoins in exchange for fiat currencies and other cryptos. Trading cannot be stopped or censored because the system is peer to peer. There is no need to register or be approved by a central authority. Another great thing is that Bisq never holds users’ funds and it has a decentralized arbitration system with security deposits to protect traders. The communication is routed over Tor and is encrypted from end to end. Bisq is also incredibly easy to use because it has a friendly interface.
