Onederx is an Estonian exchange which wasn't actually released until recently. It is recognized by the ticker name BTCUSD_P. It is a Bitcoin oriented exchange with it's major market as Bitcoin. I haven't had much of a contact and experience with it but I know for sure that it isn't popular and might actually be a closing exchange
It accepts both crypto and Fiat deposit and also withdrawal. The fees for a maker is 0.06% and 0.01 for a taker (on rebate). This exchange doesn't even have much publicly accessible information and isn't active
I heard from other users in my recent survey that the site of this exchange is not working properly and has problems with it's network server. There hasn't even been active on most review platforms and social
