Richamster is one of the exchanges I have used and enjoyed but it has a low trading volume. It's trading volume is $4.18 thousand per day. It supported crypto and Fiat currencies when I used it. But,it supports majorly crypto currencies. The number of crypto currency it supports is about thirteen and about 2 Fiats-- USD and UAH
It was developed in Ukraine and supports about 80 languages. There is one interesting characteristic about this centralized exchange,is it's affliate program. Through it, I have in many instances, added to the income I am making through the exchange. It is active and posts on all it's social media platforms such as Twitter, Facebook, Telegram, Discord . The native token of the richamster exchange is the KUB but it isn't really popular
