The migration seems to have started 2 months ago... I'm no expert but for a small exchange site it seems to be taking too long, no?
It's also shady that they have only announced such a big update in their telegram making most of their users in the dark, and this was during not prior. Even if they don't exit scam, this is still without a doubt a shady behavior.
The whois of their website is hidden but refer to American servers (by chance?) ideal for international lawsuits.
Cloudflare makes it possible to hide the server IP by acting as a proxy so that's not them but cloudflare.
EOSex. This is exactly the same excuse they gave back then when their site went offline in the Telegram group. People waited for months and months until they gave up
Also reminds me of coinsmarkets who had the same excuse. Now that I think about it, it was up from time to time, maybe to appear genuine. I say there's a fair chance vinex might do the same so check them as many times a day @op.
