With volumes of over $70 Million, I can't say Leverj is not popular among those who knows their thing. This Futures DEX appears to have been in existing for some time now, and has ammased a good following from it's clique of users. The way this exchange has been sponsored to function, it allows for gas fees to be paid in zero despite Ethereum burgeoning fees and liquidity isn't an issue to them.
The interface this exchange provides surprisingly is very similar to that if the centralised ones, with charts and indicators everywhere to do just that which is required (analysis). Through a platform called Gluon, which is built into the Layer 2 substrate of the Ethereum Blockchain, zero gas fees are paid, but high throughput for speed isn't compromised.
Another noticeable factor for the Futures DEX of Leverj is the high leverage it exposes the users to thereby offering them a higher potential of making or loosing it. No personal data is needed to use the exchange being it's decentralised nature and makes the platform a more suitable place to begin trades.
As for the Leverj token, I couldn't find much utility of the token there except for the staking of it for rewards and a portion paid out to holders as fee profit sharing.
I liked the idea behind this project and I have so far executed a number of trades here, and with only Bitcoin and Ethereum being the main and only options to trade on through Leverj, it's just that many of the popular other options we have to leverage trade on centralised exchanges are not yet available to use on Leverj, though it's Gradual process, am sure they will increase more options
