Ovis exchange comes from turkey in the year 2017, as a centralized exchange. This exchange has done well in terms of it trading fee charged. The exchange is not more available. I was unable to reach the exchange, so they are many things I will not talk on about this exchange, like the interface since I didn't have access to the exchange. Also the customer support teams are not doing well at all, they don't response to any person's complaint or message. The only fiat supported was only Turkish lira. The exchange allowed deposits via crypto currencies though. This exchange didn't even give a good reason for it closure, it only stated that it was going for an upgrade since 2018. Please the exchange is not suitable any longer. Stay away from the exchange.
