Around 16,600 to 16,700 ravencoins. The DEX shut down but they didn't notify me and I'm just trying to retrieve my funds back.
No, you can't
The deadline was 15 December 2019, you already late buddy! just let it go there is no way to get back your token because they already dead and shutting down their service + server. Feels bad for you! just take some lessons from this to never leave any of your fund on exchange when you want to hold it in a longer-term, created your own wallet then you can backup to leave it for the longer term.
I remembered, cryptobridge register never put any email so you not getting some information while they are clossing. They only give some information from their social media and website but right now already closed.
