Derivatives DEX – Decentralized derivatives exchange will be my target. Why? Because on this I can get data on-chain the entire history of a trader and their real-time behavior. Since on-chain everything is transparent. Unlike the “group call bets” that only show all winning orders. Among the derivatives dex, I will choose GMX. Because: 1. This is the exchange with the largest volume in the derivatives dex array. 2. There is the largest community, so there are many tools and bots to support.
