According to research and reviews from various authors, payrue is an exchange that has been in action since 2018. But the content of this exchange are not enough to backup this exchange.
This exchange was shared to me last month, I couldn't trade nor invest in this exchange, because I wasn't much convinced about this exchange. From all indications, payrue Dex exchange has been underperforming since entering the exchange world.
The trading volume of this exchange is very low, considering the amount of time it has spent in the Crypto market. Also, accessing the main page of this exchange is another challenge of it's own. It is believed that this exchange is dead or at the point of shutting down.
