Today is the best solution exchange IDEX
That's the most popular decentralized exchange now, but the volume has really gone down because the interest of ETH tokens has also dropped.
Currently, trading volume now is $1,753,150 USD but I hope a new competitor will operate in the market and will not only be limited for ETH and its tokens.
As of now, the price of ETH is really struggling at the current value which makes many potential coins losing their value in the market. From my experience, IDEX is very good decentralised exchange when compared to other exchanges out there in the market.
