If developers or community managers are so inactive in this project, then I think this project will be dead soon. Tangerine's team, can you do something about this? We need more news more updates and even chatting with us in a telegram group is fine.
It seems to be dead already. This 'exchange' launched in late December is essentially a mockup. There are no trades, order books are empty, no ways to deposit or withdraw fiat. I think nobody is going to use it, even if it works.
