It will possibly be a popular in due time. Since deFi are on hype, investors are riding in the trend thus decentralized margin trading are also hyping. One example is that
ddex platform.
Been using bitmex and binance for margin trading. But that defi margjn trading platform hooked me. Ive traded there once and I can say it is a smooth experience. If this one continue to be chosen by margin traders, not long that it will be famous, too.
