To determine the best Decentralized exchange is not easy enough. For one thing, there are currently hundreds of decentralized exchanges out there and the number continues to grow. Also, different decentralized exchanges offer different features and may work differently. To evaluate it, you must consider many factors, such as security, ease of use, a speed of trade, trading volume, liquidity, the number of crypto assets that can be traded, etc. In my opinion, IDEX is decentralized exchange currently the most widely used. Therefore, maybe the best.
